A hardware order lists a bolt priced at $2.35, a matching nut at $0.60, and a washer at $0.15. If 40 complete sets are bought, what is the total cost?

Correct answer to question 142 (Arithmetic Reasoning): $124.00

Method

Find the cost of one complete set before scaling up. One set costs 2.35 + 0.60 + 0.15 = $3.10, and 40 sets cost 40 x 3.10 = $124.00.
