or multiplying by a number which goes in both rates
Whole-wheat bread = $2.06/lb
We need the cost of 3.8 lbs of whole-wheat bread.
So, we simply need to multiply the cost with the amount needed.
(cost per pound) × (amount of bread)
($2.06) × (3.8)
Simplify.
$7.828
Round to the nearest tenths.
$7.83
So, 3.8 pounds of whole wheat bread costs $7.83
