Isaac paid $75 for 15 hamburgers at the local supermarket for a family
party. Tomorrow the cost per hamburger goes down by $0.50. If his dad
goes to the same place tomorrow to pick up more hamburgers, how
much should he pay for 8 hamburgers?
Step-by-step explanation: Divide 75 by 15, which gives you a cost of $5 per burger. If the cost goes down by 50 cents, you’re left with $4.50 per burger. Multiply this by 8 to get $36.
