Ben saved $12 each day and Zoe saved $
h more than Ben each day. After 2 weeks, they were still short of $29 to buy a computer.
- How much did the computer cost? Express your answer in terms of h.
- If h = $17, how much did the computer cost?
(a)
Amount Ben saved per day = $12
Amount Zoe saved per day = $(12 +
h)
Total amount both saved per day
= 12 + 12 +
h = $(24 +
h)
Number of days in 2 weeks
= 2 x 7
= 14
Total both saved in 2 weeks
= 14(24 +
h)
= 14 x 24 + 14 x
h = $(336 + 14
h)
Cost of the computer
= 336 + 14
h + 29
= 336 + 29 + 14
h= $(365 + 14
h)
(b)
If
h = $17,
Cost of the computer
= 365 + 14 x 17
= 365 + 238
= $603
Answer(s): (a) $(365 + 14
h) or $(14
h + 365); (b) $603
