Question

Mental Math Sparky went shopping at Wally World and bought a pair of socks for $2.50, a pair of jeans for $14.95, and some shoes for $12.50. How much did Sparky spend during his shopping spree?

Answer 1

$29.95

Explanation:

The 2.50 conveniently adds with 12.50 to make 15.00. The 14.95 is 5¢ less than 15.00, so the sum will be 5¢ less than 2·15.00 = 30.00.

Sparky spent $29.95 during his shopping spree.
