Question

Mrs Wong bought a rice cooker for $126 after a discount of 30%.

(a) What was the price of the rice cooker before discount? (b) She paid $40 for a toaster. The total discount for the rice cooker and the toaster was $64. What was the percentage discount given for the
toaster?​

Answer 1

(a) $180

(b) 25%

Explanation:

(a) $126 = 30% of x; x is the total

so from this, you get an equation: 126 = 0.3x

solve the equation: x = 180; so the amount before

discount is $180

(b) You know the price of discount for the rice cooker is

180-126 which is $54

Then you subtract 54 from 64 to get the discount amount for the toaster

10/40 is 1/4 or 25%
