Bobby bought 1.12 pounds of turkey at $2.50 per pound. He spent:
1.12 * $2.50 =$2.80
Carla bought 1.4 pounds of turkey at $2.20 per pound. She spent:
1.4 * $2.20 = $3.08
We can see Carla spent more than Bobby
The difference between their costs is:
$3.08 - $2.80 = $0.28
Carla spent $0.28 more than Bobby
