Question

Enter the correct answer in the box. Write your answer in the form at + bm = c.

Answer 1

t + m ≤ 11

Explanation:

The total weight will be the sum of the weights of the bags present. The weight of t bags of topsoil will be 30t; the weight of m bags of mulch will be 30m. We want the total weight to be at most 330. (Weight numbers are in pounds.)

30t +30m ≤ 330

We can remove a factor of 30 to simplify this to ...

t + m ≤ 11
