Albert saved $11 each day and Rachel saved $
y more than Albert each day. After 5 weeks, they were still short of $28 to buy a television set.
- How much did the television set cost? Express your answer in terms of y.
- If y = $10, how much did the television set cost?
(a)
Amount Albert saved per day = $11
Amount Rachel saved per day = $(11 +
y)
Total amount both saved per day
= 11 + 11 +
y = $(22 +
y)
Number of days in 5 weeks
= 5 x 7
= 35
Total both saved in 5 weeks
= 35(22 +
y)
= 35 x 22 + 35 x
y = $(770 + 35
y)
Cost of the television set
= 770 + 35
y + 28
= 770 + 28 + 35
y= $(798 + 35
y)
(b)
If
y = $10,
Cost of the television set
= 798 + 35 x 10
= 798 + 350
= $1148
Answer(s): (a) $(798 + 35
y) or $(35
y + 798); (b) $1148
