Elijah saved $9 each day and Cindy saved $
h more than Elijah each day. After 5 weeks, they were still short of $28 to buy a printer.
- How much did the printer cost? Express your answer in terms of h.
- If h = $17, how much did the printer cost?
(a)
Amount Elijah saved per day = $9
Amount Cindy saved per day = $(9 +
h)
Total amount both saved per day
= 9 + 9 +
h = $(18 +
h)
Number of days in 5 weeks
= 5 x 7
= 35
Total both saved in 5 weeks
= 35(18 +
h)
= 35 x 18 + 35 x
h = $(630 + 35
h)
Cost of the printer
= 630 + 35
h + 28
= 630 + 28 + 35
h= $(658 + 35
h)
(b)
If
h = $17,
Cost of the printer
= 658 + 35 x 17
= 658 + 595
= $1253
Answer(s): (a) $(658 + 35
h) or $(35
h + 658); (b) $1253
