Flynn saved $8 each day and Xandra saved $
k more than Flynn each day. After 5 weeks, they were still short of $29 to buy a printer.
- How much did the printer cost? Express your answer in terms of k.
- If k = $11, how much did the printer cost?
(a)
Amount Flynn saved per day = $8
Amount Xandra saved per day = $(8 +
k)
Total amount both saved per day
= 8 + 8 +
k = $(16 +
k)
Number of days in 5 weeks
= 5 x 7
= 35
Total both saved in 5 weeks
= 35(16 +
k)
= 35 x 16 + 35 x
k = $(560 + 35
k)
Cost of the printer
= 560 + 35
k + 29
= 560 + 29 + 35
k= $(589 + 35
k)
(b)
If
k = $11,
Cost of the printer
= 589 + 35 x 11
= 589 + 385
= $974
Answer(s): (a) $(589 + 35
k) or $(35
k + 589); (b) $974
