Answer:

9 carnations, and 6 roses

Explanation:

Let x be the number of carnations in the bouquet.

This means the roses will be 15 - x, since both the carnations and the roses equal 15 flowers.

Write an equation:

.8x + 1.25(15-x) = 14.7

.8x + 18.75 - 1.25x = 14.7

.45x = 4.05

x = 9

This means there will be 9 carnations, and 6 roses.

Hope this helps!
