Jeremy saved $12 each day and Gabby saved $
p more than Jeremy each day. After 6 weeks, they were still short of $32 to buy a massage chair.
- How much did the massage chair cost? Express your answer in terms of p.
- If p = $14, how much did the massage chair cost?
(a)
Amount Jeremy saved per day = $12
Amount Gabby saved per day = $(12 +
p)
Total amount both saved per day
= 12 + 12 +
p = $(24 +
p)
Number of days in 6 weeks
= 6 x 7
= 42
Total both saved in 6 weeks
= 42(24 +
p)
= 42 x 24 + 42 x
p = $(1008 + 42
p)
Cost of the massage chair
= 1008 + 42
p + 32
= 1008 + 32 + 42
p= $(1040 + 42
p)
(b)
If
p = $14,
Cost of the massage chair
= 1040 + 42 x 14
= 1040 + 588
= $1628
Answer(s): (a) $(1040 + 42
p) or $(42
p + 1040); (b) $1628
