George saved $11 each day and Xandra saved $
e more than George each day. After 5 weeks, they were still short of $32 to buy a massage chair.
- How much did the massage chair cost? Express your answer in terms of e.
- If e = $5, how much did the massage chair cost?
(a)
Amount George saved per day = $11
Amount Xandra saved per day = $(11 +
e)
Total amount both saved per day
= 11 + 11 +
e = $(22 +
e)
Number of days in 5 weeks
= 5 x 7
= 35
Total both saved in 5 weeks
= 35(22 +
e)
= 35 x 22 + 35 x
e = $(770 + 35
e)
Cost of the massage chair
= 770 + 35
e + 32
= 770 + 32 + 35
e= $(802 + 35
e)
(b)
If
e = $5,
Cost of the massage chair
= 802 + 35 x 5
= 802 + 175
= $977
Answer(s): (a) $(802 + 35
e) or $(35
e + 802); (b) $977
