Ken bought $656 worth of post-it pads and correction tapes. He bought thrice as many correction tapes as post-it pads. He spent $160 more on correction tapes than on post-it pads. Each post-it pad cost $1.40 more than each correction tape. Find the price of a post-it pad.
(a)
Total amount that the post-it pads cost
= (656 - 160) ÷ 2
= 496 ÷ 2
= $248

Total amount that the correction tapes cost
= 656 - 248
= $408

Number of sets of correction tapes = 3
Number of sets of post-it pads = 1

Cost of 1 set of correction tapes
= 408 ÷ 3
= $136

Amount that 1 set of post-it pads cost more than 1 set of correction tapes
= 248 - 136
= $112

Number of items in 1 set
= 112 ÷ 1.40
= 80

Price of a post-it pad
= 248 ÷ 80
= $3.10

Answer(s): $3.10
