Jenson saved $10 each day and Barbara saved $
g more than Jenson each day. After 4 weeks, they were still short of $32 to buy a television set.
- How much did the television set cost? Express your answer in terms of g.
- If g = $18, how much did the television set cost?
(a)
Amount Jenson saved per day = $10
Amount Barbara saved per day = $(10 +
g)
Total amount both saved per day
= 10 + 10 +
g = $(20 +
g)
Number of days in 4 weeks
= 4 x 7
= 28
Total both saved in 4 weeks
= 28(20 +
g)
= 28 x 20 + 28 x
g = $(560 + 28
g)
Cost of the television set
= 560 + 28
g + 32
= 560 + 32 + 28
g= $(592 + 28
g)
(b)
If
g = $18,
Cost of the television set
= 592 + 28 x 18
= 592 + 504
= $1096
Answer(s): (a) $(592 + 28
g) or $(28
g + 592); (b) $1096
