a school club is having a bake sale and uses the formula p=5x+3y to determine the profit ,p, for selling x cupcakes and y brownies. Which formula can be used to determine the number of cupcakes sold , given p and y?

The formula that can be used to determine the number of cupcakes sold is x = 0.2p - 0.6y.

Step-by-step explanation:

Given:

p = 5x+3y (1)

The formula that can be used to determine the number of cupcakes sold, i.e. x, given p and y, can be obtain by solving for x in equation (1) above as follows:

5x = p - 3y

Divide through by 5, we have:

x = P/5 - (3/5)y

x = (1/5)p - (3/5)y

x = 0.2p - 0.6y

Therefore, the formula that can be used to determine the number of cupcakes sold is x = 0.2p - 0.6y.

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
