Bobby bought $804 worth of correction tapes and staplers. He bought thrice as many staplers as correction tapes. He spent $396 more on staplers than on correction tapes. Each correction tape cost $2.10 more than each stapler. Find the price of a correction tape.
(a)
Total amount that the correction tapes cost
= (804 - 396) ÷ 2
= 408 ÷ 2
= $204

Total amount that the staplers cost
= 804 - 204
= $600

Number of sets of staplers = 5
Number of sets of correction tapes = 1

Cost of 1 set of staplers
= 600 ÷ 5
= $120

Amount that 1 set of correction tapes cost more than 1 set of staplers
= 204 - 120
= $84

Number of items in 1 set
= 84 ÷ 2.10
= 40

Price of a correction tape
= 204 ÷ 40
= $5.10

Answer(s): $5.10
