rachel made 104 in 8 hours

at this same rate how many hours would she have to work to make 234

To find out how many hours Rachel would have to work to make 234, we can set up a proportion.

104 points earned in 8 hours
234 points earned in x hours

104 / 8 = 234 / x

Cross multiply:
104x = 1872

Divide by 104:
x = 18

Therefore, Rachel would have to work 18 hours to make 234 points.
