Question

Christa buys 14 flowerpots. Some are small and cost $2.40 each. The rest are large and cost $5.60 each. She spends a total of $49.60.

Which equation models this situation?

Let s represent the number of small flowerpots she buys.


A.
5.6s + 2.4(s + 14) = 49.6

B.
(2.4 + 9.6)(14 – s) = 49.6

C.
2.4s + 5.6(14 – s) = 49.6

D.
5.6s + 2.8(14) = 49.6
