Complete question :

shopkeeper sells one machine for 990 re at a profit of 10% and another machine for 1960 at a loss of 2%. What is his gain or loss percent

Answer:

1.72%

Step-by-step explanation:

Given that :

MACHINE 1:

Sales price = 990

Profit percent = 10%

The cost price of the machine (x) :

10% profit of x :

(100 + 10)% of x = 990

110% of x = 990

1.1x = 990

x = 990/1.1

x = 900

MACHINE 2:

Sales price = 1960

Loss on sale = 2%

Cost price (x) :

(100 - 2)% of x = 1960

98% x = 1960

0.98x = 1960

x = 1960/0.98

x = 2000

Total amount realized from sale = (990 + 1960) = 2950

Total cost of production = (2000 + 900) = 2900

Profit Made = (2950 - 2900) = 50

% profit:

(Profit / cost of production) * 100

(50 / 2900) * 100%

0.0172413 * 100%

profit % = 1.72

The profit made is 50

Cost price of first machine will be:

= 100/(100 + 10) × 990

= 100/110 × 990

= 100 × 9

= 900

Cost price for second machine will be:

= (100 - 2) × x = 1960

= 98% × x = 1960

= 0.98x = 1960

x = 1960/0.98.

x = 2000

The total cost price = 900 + 2000 = 2900

Total selling price = 990 + 1960 = 2950

Therefore, profit will be:

= Selling price - Cost price .

= 2950 - 2900

= 50

Answer:

[tex]1.794 \times {10}^{2} [/tex]

(in scientific notation)

Answer:

x=4

Step-by-step explanation:

Step 1: Add 3x to both sides.

−5x+9+3x=−3x+1+3x

−2x+9=1

Step 2: Subtract 9 from both sides.

−2x+9−9=1−9

−2x=−8

Step 3: Divide both sides by -2.

−2x/−2=−8/−2

Answer:

yes D is right... brainliest plz

Answer:

idk

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Find the slope using the formula [ y2-y1/x2-x1 ]

2-2/-5-3

0/-8

0

Find the y-intercept using slope-intercept form [ y = mx + b ] and (3, 2)

y = 0x + b

2 = 0(3) + b

2 = b

Put everything we know into the final form.

y = 0x + 2

y = 2

Best of Luck!

change in y/change in x

y2-y1/x2-x1

2-2/-5-3

0/-8 = 0

The slope is 0 - the answer is d

because when 0x = 0, then you are left with y and only y

when the equation is x=, then the equation is undefined

but, when an equation is y=, that the slope is 0

Answer:

Chau drove 139 miles

Step-by-step explanation:

Knowing how much Chau spent at the end makes the question much much easier. So what you want to do is take of the base fee ($20.99) off the final amount he had to pay.

$130.80 - $20.99 = $109.81

Now you divide $109.81 by the additional charge ($0.79)

Change the divisor (0.79) to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend (109.81) the same, 2 places to the right.

We then have the equations:

10981 ÷ 79 = 139.000

and therefore:

109.81 ÷ 0.79 = 139.000

Chau drove 139 miles.

Answer:

Step-by-step explanation:

It’s the answer I did the math

The unit rate for the ratio is 3 laps per miles.

Given that the ratio is 78 laps/26 miles.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Now,

Unit rate =78 laps/26 miles

Divide both the numerator and the denominator by 26.

So, 78 laps÷26 miles/26 miles÷26 miles

= 3 laps/miles

Therefore, the unit rate for the ratio is 3 laps per miles.

Answer:

x < -20

Step-by-step explanation:

[tex]\frac{x}{5}[/tex] + 6 < 2

subtract 6 from both sides of the equation

[tex]\frac{x}{5}[/tex] < 2 - 6

[tex]\frac{x}{5}[/tex] < -4

multiply both sides of the equation by 5

x < -4 * 5

x < -20
