one large cake and some cupcakes and needs to find the best place to buy them
from. Riverside Bakery charges $2 for each cupcake, plus $59 for the large cake.
The Sweet Shoppe charges $38 for the large cake and $3 for each cupcake.
If she wants to buy 30 cupcakes, which place would be cheaper for her to buy
from? How do you know?

Answer 1

Explanation:

Riverside Bakery charges $2 for each cupcake, plus $59 for the large cake.

The Sweet Shoppe charges $38 for the large cake and $3 for each cupcake.

(riverside)

$59 + $2(30) =$119

(sweet shoppe)

38 + $3(30) =$128

riverside bakery is cheaper
