Question

Amy planted a flower garden with rows of blue flowers, b, and rows of yellow flowers, y. Each row of blue flowers has 5 flowers, and each row of yellow flowers has 7 flowers. Which expression represents the total number of flowers Amy planted?

A. 5 + r + 7 + b
B. 5b + 7y
C. 5 × 7 + b × y
D. 5y + 7b

Answer 1

This problem has two variables, b and y. The b value is the number of rows of blue flowers, and the y value is the number of rows of yellow flowers.

In every row of blue, there are 5 flowers.

In every row of yellow, there are 7 flowers.

Therefore, our expression would be 5b + 7y.

I hope this answers your question.
