Tom and Sam went to buy printers at a sale. The usual price of 1 printer was $1600 each.
SALEBuy 1 printer at 10% discount
Buy 2 or more printers at 25% discount each
- Tom bought 1 printer. How much did he pay?
- What is the maximum number of printers Sam can buy if he has $5000?
(a)
Discounted price of 1 printer in percent if only 1 was bought
= 100% - 10%
= 90%
100% of 1 printer = 1600
1% of 1 printer = 1600 ÷ 100 = 16
90% of 1 printer = 90 x 16 = 1440
Amount that Tom paid for 1 printer = $1440
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 25%
= 75%
75% of 1 printer = 75 x 16 = 1200
Amount that Sam paid for 1 printer = $1200
Maximum number of printers that Sam can buy if he has $5000
= 5000 ÷ 1200
= 4 r 200
Answer(s): (a) $1440; (b) 4
