Question

Mr. Guy pens and pencils. He spends a total of $25. Each pencil cost $1 and each pen cost

$1.50. Use X to represent the number of pencils. Use Y to represent the number of pens. Write an
equation that represents the situation

Answer 1

x + 1.5y = 25

Explanation:

Given that Mr. Guy spends a total of $25, we can set the equation equal to 25. Since x is used to represent the number of pencils, we put 1x into the left side of the equation. We also know that it cost $1.50 for each y pens, therefore 1.5y. If we put together what we have, the equation will be x + 1.5y = 25.
