Natalie needs to save $479.58 for a vacation. She saved $149.88, and earns $7.85 an hour working at the grocery store. How many hours must she work to meet her goals?

42 hours

Step-by-step explanation:

Natalie needs to save a total of $479.58

She already saved $149.98

The amount left to save is

If she earns 7.85 dollars working per hour then the number of hours she can work to get $329.7 can be calculated as follows

= 329.7 / 7.85

= 42

Hence Natalie will work for 42 hours to meet her goals
