A shopkeeper bought 52 eggs. She threw away 7 rotten eggs and sold the rest at $0.80 for 5 eggs. How much money did she collect in all after selling the eggs?
Solution
52 – 7 = 45 (eggs sold)
45 eggs divided by 5 eggs ----- 9 sets of 5 eggs
1 set ----- $0.80
9 sets ----- 9 x $0.80 = $7.20
Answer: She collected $7.20.
