Vincent bought $774 worth of foolscaps and correction tapes. He bought thrice as many correction tapes as foolscaps. He spent $446 more on correction tapes than on foolscaps. Each foolscap cost $2.10 more than each correction tape. Find the price of a foolscap.
(a)
Total amount that the foolscaps cost
= (774 - 446) ÷ 2
= 328 ÷ 2
= $164

Total amount that the correction tapes cost
= 774 - 164
= $610

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

Cost of 1 set of correction tapes
= 610 ÷ 5
= $122

Amount that 1 set of foolscaps cost more than 1 set of correction tapes
= 164 - 122
= $42

Number of items in 1 set
= 42 ÷ 2.10
= 20

Price of a foolscap
= 164 ÷ 20
= $8.20

Answer(s): $8.20
