Sean saved $8 each day and Hazel saved $
s more than Sean each day. After 6 weeks, they were still short of $32 to buy a tablet.
- How much did the tablet cost? Express your answer in terms of s.
- If s = $20, how much did the tablet cost?
(a)
Amount Sean saved per day = $8
Amount Hazel saved per day = $(8 +
s)
Total amount both saved per day
= 8 + 8 +
s = $(16 +
s)
Number of days in 6 weeks
= 6 x 7
= 42
Total both saved in 6 weeks
= 42(16 +
s)
= 42 x 16 + 42 x
s = $(672 + 42
s)
Cost of the tablet
= 672 + 42
s + 32
= 672 + 32 + 42
s= $(704 + 42
s)
(b)
If
s = $20,
Cost of the tablet
= 704 + 42 x 20
= 704 + 840
= $1544
Answer(s): (a) $(704 + 42
s) or $(42
s + 704); (b) $1544
