Full solution

Q. Jane can buy daffodil bulbs in packages of 33 for $7.17\$7.17 or in packages of 22 for $5.64\$5.64. How much money does she save by buying 66 bulbs at the better price? $\$ \square
  1. Calculate cost of 66 bulbs: Calculate the cost of 66 bulbs in packages of 33. 33 bulbs cost $7.17\$7.17, so 66 bulbs cost 22 * $7.17\$7.17. 22 * $7.17\$7.17 = $14.34\$14.34
  2. Calculate cost of 66 bulbs: Calculate the cost of 66 bulbs in packages of 22. 22 bulbs cost $5.64\$5.64, so 66 bulbs cost \(3 * $5.64\$5.64\). \(3 * $5.64\$5.64 = $16.92\$16.92\)
  3. Find cost difference: Find the difference in cost.$16.92$14.34=$2.58\$16.92 - \$14.34 = \$2.58
