Correct Answer: D
Explanation:
The total savings in purchasing thirty 13-cent lollipops for a class party at a reduced rate of $1.38 per dozen is:
Cost of 30 lollipops at original price = 0.13 × 30 =$3.90
Cost of 30 (2.5 dozens) at reduced price = 1.38 × 2.5 = $3.45
Saving = Cost at Original Price - Total cost at reduced price
Saving = 3.9 - 3.45 = 0.45
