Fred saved $9 each day and Hazel saved $
h more than Fred each day. After 5 weeks, they were still short of $29 to buy a tablet.
- How much did the tablet cost? Express your answer in terms of h.
- If h = $4, how much did the tablet cost?
(a)
Amount Fred saved per day = $9
Amount Hazel 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 tablet
= 630 + 35
h + 29
= 630 + 29 + 35
h= $(659 + 35
h)
(b)
If
h = $4,
Cost of the tablet
= 659 + 35 x 4
= 659 + 140
= $799
Answer(s): (a) $(659 + 35
h) or $(35
h + 659); (b) $799
