Micro is paid `$80` per day plus `$15` per hour for overtime. If he works five days per week and wants to make a minimum of `$520` this week, what is the fewest number of hours of overtime he must work ?

Answer

8

Explanation

Translate from English into math to crate an inequality in Which h represents the number of hours of overtime Marco must work. Macro gets paid a daily wage plus an hourly rate for overtime, so his weekly pay is his daily rate `($80)` times 5 days, plus the number of hours of overtime he works (h) times his overtime rate `($15).` If he wants to make at least `$520,` which means that much or more, the inequality is
`(80xx5) + 15hge 520.` Solve for h:
`400+15hge 520`
`15h ge 120`
`h ge 8`
Macro must work at least 8 hours of overtime to make `$520` or more this week. Grid in 8.
