Tim saved $11 each day and Rachel saved $
m more than Tim each day. After 5 weeks, they were still short of $28 to buy a printer.
- How much did the printer cost? Express your answer in terms of m.
- If m = $11, how much did the printer cost?
(a)
Amount Tim saved per day = $11
Amount Rachel 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 printer
= 770 + 35
m + 28
= 770 + 28 + 35
m= $(798 + 35
m)
(b)
If
m = $11,
Cost of the printer
= 798 + 35 x 11
= 798 + 385
= $1183
Answer(s): (a) $(798 + 35
m) or $(35
m + 798); (b) $1183
