Mrs Wong bought a rice cooker for $126 after a discount of 30%.
jarptica [38.1K]

Answer:

(a) $180

(b) 25%

Step-by-step 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%
