Daniel saved $11 each day and Hilda saved $
m more than Daniel each day. After 5 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 m.
- If m = $19, how much did the television set cost?
(a)
Amount Daniel saved per day = $11
Amount Hilda saved per day = $(11 +
m)
Total amount both saved per day
= 11 + 11 +
m = $(22 +
m)
Number of days in 5 weeks
= 5 x 7
= 35
Total both saved in 5 weeks
= 35(22 +
m)
= 35 x 22 + 35 x
m = $(770 + 35
m)
Cost of the television set
= 770 + 35
m + 32
= 770 + 32 + 35
m= $(802 + 35
m)
(b)
If
m = $19,
Cost of the television set
= 802 + 35 x 19
= 802 + 665
= $1467
Answer(s): (a) $(802 + 35
m) or $(35
m + 802); (b) $1467
