C. Plumber A and Plumber B will both charge $135 if they each work 2.5 h.
8 so it would be 2/8 plus 3/8
56 times!!
This is because the exponent indicates how many times you multiply a number. For example:
5^2= 5x5
If $0.35=1 ounce
?=8.5 ounces
8.5/1*$0.35=$2.975 Therefore 8.5 ounces cost $2.975
If 1 ounce =$0.35
12.2 ounces=?
12.2/1*$0.35=$4.27
Therefore 12.2 ounces cost $4.27
