Question

Jahangir buys a squash racquet, originally marked $40, that is discounted by 20%.

He also has a loyalty card that gives him another 25% off the sale price.

What is the final cost of the squash racquet?

Worked Solution

Solution 1
Sale price = 40 −- (20% × 40)
= $32

∴\therefore Final cost = 32 −- (25% × 32)
= $24

Solution 2 (advanced)
Final cost = 40 × 0.80 × 0.75
= $24
