Fabian and Mark went to buy television sets at a sale. The usual price of 1 television set was $1800 each.

SALE
Buy 1 television set at 5% discount
Buy 2 or more television sets at 15% discount each

1. Fabian bought 1 television set. How much did he pay?
2. What is the maximum number of television sets Mark can buy if he has $6000?

(a)
Discounted price of 1 television set in percent if only 1 was bought
= 100% - 5%
= 95%

100% of 1 television set = 1800
1% of 1 television set = 1800 ÷ 100 = 18
95% of 1 television set = 95 x 18 = 1710 

Amount that Fabian paid for 1 television set = $1710

(b)
Discounted price of 1 television set in percent if more than 1 was bought
= 100% - 15%
= 85%

85% of 1 television set = 85 x 18 = 1530

Amount that Mark paid for 1 television set = $1530

Maximum number of television sets that Mark can buy if he has $6000
= 6000 ÷ 1530
= 3 r 1410

Answer(s): (a) $1710; (b) 3
