Question

find the unit rate:
4 pounds of apples is $1.96

sal washed 5 cars in 50 minutes

Answer 1

For both, the best thing to do is to divide the total time or cost, by the amount.
$1.96/4= $0.49
50/5= 10
Therefore, the unit rate of one pound of apples is $0.49 & the unit rate is 1 car in ten minutes
Hope this helps :)
