Tom and Will went to buy television sets at a sale. The usual price of 1 television set was $1900 each.

SALE
Buy 1 television set at 10% discount
Buy 2 or more television sets at 15% discount each

1. Tom bought 1 television set. How much did he pay?
2. What is the maximum number of television sets Will can buy if he has $5000?

(a)
Discounted price of 1 television set in percent if only 1 was bought
= 100% - 10%
= 90%

100% of 1 television set = 1900
1% of 1 television set = 1900 ÷ 100 = 19
90% of 1 television set = 90 x 19 = 1710 

Amount that Tom 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 19 = 1615

Amount that Will paid for 1 television set = $1615

Maximum number of television sets that Will can buy if he has $5000
= 5000 ÷ 1615
= 3 r 155

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