Solutions

Better Buy: Buying More Than One

  1. Kitchen Place; \$36 \div 6 = \$6 for one mug at KitchenPlace, and \$28 \div 4 - \$7 for one mug at Dane’s Dishes. The difference in price of one mug is $1 so 2 mugs would be $2 less.
  2. Dane’s Dishes; \$45 \div 5 = \$9 for one soup bowl at Dan’s Dishes, and \$50 \div 5 = \$10 for one soup bowl at KitchenPlace. The difference in price of one soup bowl is $1, so 2 bowls would be $2 less.
  3. Dane’s Dishes; \$42 \div 7 = \$6 for one water bottle at Dane’s Dishes, and \$72 \div 9 = \$8 for one water bottle at KitchenPlace. The difference in price of one water bottle is $2, so 5 water bottles would be $10 less.
