Beach Bicycles sells two-seater bicycles. Its markup rate is 68%. Which equation represents the new price for a bicycle, y, given an original price, x?
Answer:
y = 1.68x
Step-by-step explanation:
The markup rate of a product or service refers to how higher the selling price is than the total production cost. In this case, this company doesn't produce the bikes, instead it purchases them from a wholesaler, distributor or even the factory, and then resells them in order to make a profit.
E.g. Beach Bicycles purchases two-seater bikes at $200 each, and then it will resell them to their customers at 1.68 x $200 = $336. The total markup in this example is $136, which represents $136/$200 = 68% of the purchase price.
y - 1 > -7 A.y ≥ -6 B.y > -6 C.y -8

Aubrey is saving up to buy a new jacket. She already has $85 and can save an
additional $7 per week using money from her after school job. How much total
money would Aubrey have after 8 weeks of saving? Also, write an expression that
represents the amount of money Aubrey would have saved in w weeks.
I
Aubrey can save $7 per week, so she can save $7 x 8 or $56
in 8 weeks. Because she already had $85 to begin with, the
total amount saved would be $56 + $85 or $141.
Answer:
[tex]Total\ Savings = 85 + 7 w[/tex] --- In w weeks
[tex]Total\ Savings = \$141[/tex] --- In 8 weeks
Step-by-step explanation:
Given
[tex]Available\ Amount = \$85[/tex]
[tex]Weekly\ Savings = \$7[/tex]
[tex]Number\ of\ weeks = 8[/tex]
Required
Determine the amount of savings in w weeks
This can be calculated as thus:
[tex]Total\ Savings = Available\ Amount + Weekly\ Savings * Number\ of\ weeks[/tex]
In this case;
w = Number of weeks
So, we have:
[tex]Total\ Savings = 85 + 7 * w[/tex]
[tex]Total\ Savings = 85 + 7 w[/tex]
When w = 8, we have
[tex]Total\ Savings = 85 + 7 * 8[/tex]
[tex]Total\ Savings = 85 + 56[/tex]
[tex]Total\ Savings = \$141[/tex]
Kim poured a 24-ounce container of orange juice into 5 cups. She poured the same amount of juice into each cup. Write a rational number that represents the amount of juice in each cup.Required to answer.Single line text.
Answer:
4.8
Step-by-step explanation:
24/5 = 4.8
A rational number is any whole number, fraction, finite decimal or repeating decimal. Therefore 4.8 = rational number.
A rational expression to represent the amount of juice in each cup is 24/5.
What is a fraction?A fraction is a part of the whole represented by a/b, where a and b are any integers.
Given, Kim divided 24 ounces of orange juice into 5 cups.
Therefore, the amount of juice in each cup is:
24/5
Hence, a rational expression to represent the amount of juice in each cup is 24/5.

Solve the following equation for x. Show each step.
5x + 2 = 3x + 4(2x - 1)
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
Start with:
[tex]5x+2=3x+4(2x-1)[/tex]
Distribute the [tex]4[/tex] into [tex](2x-1)[/tex]:
[tex]5x+2=3x+8x-4[/tex]
Combine like terms:
[tex]5x+2=11x-4[/tex]
Add [tex]4[/tex] to both sides of the equation:
[tex]5x+6=11x[/tex]
Subtract [tex]5x[/tex] from both sides of the equation:
[tex]6=6x[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]6[/tex]:
[tex]1=x[/tex]
or
[tex]x=1[/tex]

solve for the equation 6x+14=7x+8
Answer:
x = 6
Step-by-step explanation:
For this problem, we simply will isolate the x to find the value of x:
6x + 14 = 7x + 8
6x + -6x + 14 = 7x + -6x + 8
14 = x + 8
14 + -8 = x + 8 + -8
6 = x
Hence, x = 6.
Cheers.
Answer:
x=6
Step-by-step explanation:
First, subtract 6x from both sides to get:
14=x+8
Now, subtract 8 from both sides to get x alone:
6 = x

half a number decreased by three is equal to 38 less than four times the number
Answer:
10
Step-by-step explanation:
let the unknown number be x
so half of x decreased by 3 is
1/2x -3
It is equal to 38 less than 4 times the number which is x; 4x-37
THEREFORE;
½x-3 =4x -38
x-6/2 = 4x-38
cross-multiply
x-6 =8x -76
x-8x = -76+6
-7x = -70
Divide both sides by -7
So x =10

Point A is at (1,5) and point C is at (-5, – 7).
Find the coordinates of point B on AC such that AC is 6 times as long as AB.
Answer:
(0,3)
Step-by-step explanation:
This is a problem from affine geometry, so doesn’t need any concept of distance that mixes x and y coordinates. We can just take each coordinate separately.
(1,5),(−5,−7),(,),=6
Usually in these sorts of problems with unknown B we’re given the ratio AB:BC; here we have the slightly unusual and easier AB:AC.
The difference of the given points −=(6,12) .
Since =6 we know −=16(−)=(1,2)
So =−(1,2)=(1,5)−(1,2)
=(0,3)
