Peter saved $12 each day and Tammy saved $
p more than Peter each day. After 2 weeks, they were still short of $28 to buy a printer.
- How much did the printer cost? Express your answer in terms of p.
- If p = $6, how much did the printer cost?
(a)
Amount Peter saved per day = $12
Amount Tammy saved per day = $(12 +
p)
Total amount both saved per day
= 12 + 12 +
p = $(24 +
p)
Number of days in 2 weeks
= 2 x 7
= 14
Total both saved in 2 weeks
= 14(24 +
p)
= 14 x 24 + 14 x
p = $(336 + 14
p)
Cost of the printer
= 336 + 14
p + 28
= 336 + 28 + 14
p= $(364 + 14
p)
(b)
If
p = $6,
Cost of the printer
= 364 + 14 x 6
= 364 + 84
= $448
Answer(s): (a) $(364 + 14
p) or $(14
p + 364); (b) $448
