Question

Reuben buys candy that costs 8 per pound. He will buy at least 9 pounds of candy. What are the possible amounts he will spend on candy?

Answer 1

If Reuben buys 9 pounds of candy, the minimum amount he will spend is:

9 pounds * $8/pound = $72

If Reuben buys more than 9 pounds of candy, the possible amounts he will spend will depend on the exact amount of candy he buys. Let's call the amount of candy he buys "x" pounds. Then, the possible amounts he will spend can be calculated using the following inequality:

x > 9

The corresponding amounts he will spend can be calculated as follows:

Amount spent = x pounds * $8/pound

So, the possible amounts he will spend on candy are:

$72 < Amount spent < infinity

In other words, Reuben will spend at least $72 on candy, but the exact amount he will spend depends on the amount of candy he buys, which must be greater than 9 pounds.
