Question

June needs at least $575 to go on a vacation. She earns $10 an hour for babysitting and already has $252 saved for the trip. Which inequality can be used to find the number of hours she needs to babysit

Answer 1

`252 + 10h \ge 575`

Explanation:

Given

`Savings = 252`

`Target=575` -- atleast

`Earnings = \$10` per hour

Required

Represent as an inequality

Suppose that she babysits for h hours, her total earnings would be:

`Total\ Earnings = 10h`

In inequalities:

At least means
`\ge`

So, when the total earnings is added to her savings, we have:

`Savings + Total\ Earnings \ge Target`

Substitute values for Savings, Total Earnings and Target

`252 + 10h \ge 575`
