Perry saved $11 each day and Nicole saved $
p more than Perry each day. After 2 weeks, they were still short of $29 to buy a laptop.
- How much did the laptop cost? Express your answer in terms of p.
- If p = $5, how much did the laptop cost?
(a)
Amount Perry saved per day = $11
Amount Nicole saved per day = $(11 +
p)
Total amount both saved per day
= 11 + 11 +
p = $(22 +
p)
Number of days in 2 weeks
= 2 x 7
= 14
Total both saved in 2 weeks
= 14(22 +
p)
= 14 x 22 + 14 x
p = $(308 + 14
p)
Cost of the laptop
= 308 + 14
p + 29
= 308 + 29 + 14
p= $(337 + 14
p)
(b)
If
p = $5,
Cost of the laptop
= 337 + 14 x 5
= 337 + 70
= $407
Answer(s): (a) $(337 + 14
p) or $(14
p + 337); (b) $407
