Elijah saved $9 each day and Jade saved $
p more than Elijah each day. After 2 weeks, they were still short of $29 to buy a television set.
- How much did the television set cost? Express your answer in terms of p.
- If p = $11, how much did the television set cost?
(a)
Amount Elijah saved per day = $9
Amount Jade saved per day = $(9 +
p)
Total amount both saved per day
= 9 + 9 +
p = $(18 +
p)
Number of days in 2 weeks
= 2 x 7
= 14
Total both saved in 2 weeks
= 14(18 +
p)
= 14 x 18 + 14 x
p = $(252 + 14
p)
Cost of the television set
= 252 + 14
p + 29
= 252 + 29 + 14
p= $(281 + 14
p)
(b)
If
p = $11,
Cost of the television set
= 281 + 14 x 11
= 281 + 154
= $435
Answer(s): (a) $(281 + 14
p) or $(14
p + 281); (b) $435
