The function c(x) = 3x − 4 determines how many cupcakes need to be purchased for a birthday party, where x is the number of kids
at the party. The party planner uses d(c(x)) to find the amount of money to bring for the cupcake purchase. The function d(x) = 2x + 5. Solve for how much money to bring when there are 7 kids at the party
The value of x is 24 because 24-12=12 I worked it out by doing the opposite so by doing 12+12 Then the value of y is also 24 and I used the same method
