Question

The Valley High Marching Band is selling candy bars for a fundraiser. Sierra sold some candy bars. Breanna sold twice as many candy bars as Sierra. Together Sierra and Breanna sold no less than 45 candy bars. Write an inequality to represent this situation. Give three possible solutions for how many candy bars Sierra sold.

Answer 1

S ≥ 15

Explanation:

Let S be the number of candy bars Sierra sold and B be the number of candy bars Breanna sold.

We know that S + B ≥ 45 and B = 2S.

Substituting the second equation into the first equation, we get:

S + 2S ≥ 45

3S ≥ 45

S ≥ 15

Three possible solutions for how many candy bars Sierra sold are:

Sierra sold 15 candy bars

Sierra sold 16 candy bars

Sierra sold 17 candy bars
