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.
