Question

The number of cupcakes sold by a local bakery in April can be represented by the function p(x)=24x+48, where x represents the number of days the bakery was open that month..

The number of cookies sold by the same bakery in April can be represented by the function q(x)=51+32x, where x represents the number of days the bakery was open that month

Which function, ​r(x)​, represents the total number of cupcakes and cookies sold by the bakery during the month of April?


1) r(x)=80x+75

2) r(x)=56x+99

3) r(x)=75x+80

4) r(x)=8x+3

Answer 1

2) r(x)=56x+99

Explanation:

Took the test

Answer 2

r(x) = 56x + 99

Explanation:

You need to add the two equations together:

r(x) = (24x+48) + (51+32x)

r(x) = 24x + 32x + 48 + 51

r(x) = 56x + 99
