Caden saved $8 each day and Hazel saved $
s more than Caden each day. After 2 weeks, they were still short of $30 to buy a tablet.
- How much did the tablet cost? Express your answer in terms of s.
- If s = $3, how much did the tablet cost?
(a)
Amount Caden 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 2 weeks
= 2 x 7
= 14
Total both saved in 2 weeks
= 14(16 +
s)
= 14 x 16 + 14 x
s = $(224 + 14
s)
Cost of the tablet
= 224 + 14
s + 30
= 224 + 30 + 14
s= $(254 + 14
s)
(b)
If
s = $3,
Cost of the tablet
= 254 + 14 x 3
= 254 + 42
= $296
Answer(s): (a) $(254 + 14
s) or $(14
s + 254); (b) $296
