7-102.

The French club sold rose bouquets and chocolate hearts for Valentine’s Day. The roses sold for $5 and the hearts sold for $3. The number of bouquets sold was 15 more than the number of hearts sold. If the club collected a total of $339, how many of each gift was sold? Homework Help ✎

Think about using a system of equations, Let *r* = rose bouquets and *c* = chocolate hearts.

They sold 48 rose bouquets and 33 chocolate hearts.

Write both equations using *r* and *c*.

Equation #1: 5*r* + 3*c* =339,

Equation #2: *r* = *c* + 15.
