Seth saved $8 each day and Pamela saved $
p more than Seth each day. After 5 weeks, they were still short of $28 to buy a computer.
- How much did the computer cost? Express your answer in terms of p.
- If p = $7, how much did the computer cost?
(a)
Amount Seth saved per day = $8
Amount Pamela saved per day = $(8 +
p)
Total amount both saved per day
= 8 + 8 +
p = $(16 +
p)
Number of days in 5 weeks
= 5 x 7
= 35
Total both saved in 5 weeks
= 35(16 +
p)
= 35 x 16 + 35 x
p = $(560 + 35
p)
Cost of the computer
= 560 + 35
p + 28
= 560 + 28 + 35
p= $(588 + 35
p)
(b)
If
p = $7,
Cost of the computer
= 588 + 35 x 7
= 588 + 245
= $833
Answer(s): (a) $(588 + 35
p) or $(35
p + 588); (b) $833
