A music store buys a trumpet for $80. They want to make a 35% profit. What is the new price of the trumpet?

Answers

Answer: $108

Step-by-step explanation:

80 x .35 = 28

80+28= 108

35% just simply mean 35% more than the original price
So to solve this you to multiply the original cost($80) to 0.35
80(0.35)=$28
28 dollars is what they want to make in addition to the 80 they spent so
80+28=108
So the new price of the trumpet is $108 with profit

The constant of proportionality is 225.

Given that,

The number of calories burned by a 90-pound cyclist is proportional to the number of hours the cyclist rides. The equation to represent this relationship is y = 225x

Suppose a room service waitress at the Sand and Sand Resort receives gratuity represented by the equation g=0.15b, where g represents the gratuity and b represents the food bill.
If the food bill is $19, How much tip did she receive?

Answers

Answer:

$2.85

Step-by-step explanation:

So you have the equation g = 0.15b and you have that the food bill is $19, which would mean b = 19.

Then, you just have to plug that into the equation which would look like this:

[tex]g = 0.15 * 19[/tex]

0.15 * 19 = $2.85, so the gratuity, or tip, is $2.85

Suppose that you are in charge of selling hamburgers for your school fundraiser. You are selling hamburgers in your local community.
Which tray/plate should you use for the hamburgers?
How many hamburgers should you sell?
How many buns and meat patties should you buy to sell?
A styrofoam plate comes in packages of 14.
A sheet iron tray comes in packages of 12.
Buns are sold in packages of 12.
Meat patties are sold in packages of 18.
The school is counting on you to sell between 10-80 hamburgers.
You don't want any leftovers of anything.

I don't understand this question, can someone lend a hand?

Answers

Answer:

(I have first answered the 2nd question first to find out how many Iron trays I actually need)

A2-(This is kinda tricky)

If you want to make a hamburger you would want to have 2 buns and 1 patty.

So our equation will be-

x/18=2

(Also I am buying 18 patties)

(And the 2 is twice the patties I have)

x=18x2

x=36

And now to figure out how many packages (each of 12) I need to have to make Hamburgers without having any leftovers

So,

36/12

=3

Therefore I would need 3 packages of Buns

A1-The number of Sheet Iron needed,

=> Number of Sheet Iron Tray=Number of Patties Bought

= 12x=36

= x=36/12

= x=3

Therefore you would need 3 packages of Iron trays

This question actually has different answers to it this is just an example of one of its answers.
