Question

John needs a plumber to repair the kitchen drain. The plumber charges $85 for the parts that he will need for the repair plus $30 for each hour worked. The maximum amount of money john can spend is $250. Which inequality would represent this situation if x is the number of hours worked?

Answer 1

`30x+85y\leq 250`

Explanation:

Cost of each part is
`\$85`

Cost of working one hour is
`\$30`

Let number of hours worked be
`x` and

number of parts bought be
`y`.

The maximum amount of money that John can spend is
`\$250`.

From the question we have

`30x+85y\leq 250`

The required inequality is
`30x+85y\leq 250`.
