Ivanna made $414 for 18 hours of work.

At the same rate, how many hours would she have to work to make $115?

5

Step-by-step explanation:

First, we have to figure out how much money she makes per hour. We can do this by dividing. 414 divided by 18 = 23. Then, we multiply. 23 x 17 = 391, 23 x 16 = 368 etc. we multiply until we get to, 23 x 5, which equals 115. I hope this made sense!

5hours

Step-by-step explanation:

Ivanna made $414 for 18 hours of work.

Working at the same rate, she will make $115 for = (115 x 18) / 414 = 5hours
