Julian saved $9 each day and Victorium saved $
m more than Julian each day. After 4 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 m.
- If m = $9, how much did the massage chair cost?
(a)
Amount Julian saved per day = $9
Amount Victorium saved per day = $(9 +
m)
Total amount both saved per day
= 9 + 9 +
m = $(18 +
m)
Number of days in 4 weeks
= 4 x 7
= 28
Total both saved in 4 weeks
= 28(18 +
m)
= 28 x 18 + 28 x
m = $(504 + 28
m)
Cost of the massage chair
= 504 + 28
m + 32
= 504 + 32 + 28
m= $(536 + 28
m)
(b)
If
m = $9,
Cost of the massage chair
= 536 + 28 x 9
= 536 + 252
= $788
Answer(s): (a) $(536 + 28
m) or $(28
m + 536); (b) $788
