Question

Mr Teo wants to buy an oven. Which shop sells the oven at a lower price? Show your working clearly.​

Answer 1

100% - 15% = 85%
Shop A = 190 x 85% = 161.5
100% - 20% = 80%
Shop B = 200 x 80% = 160
Shop B sells the oven at a lower price.

Answer 2

Answer:

Shop B

Step-by-step explanation:

Hi there!

To solve this question, we can find the new prices of each oven and identify which one is cheaper.

Shop A

Usual price: $190

Discount: 15%

First, we must subtract the discount percent from 100:

100 - 15 = 85

Therefore, the new price of the product will be 85% of the original price. Find 85% of $190:

190 × 0.85

Therefore, the new price is $161.50.

Shop B

Usual price: $200

Discount: 20%

Again, subtract 20 from 100:

100 - 20 = 80

This means that the new price of the oven is 80% of the original price:

200 × 0.8 = 160

Therefore, the new price is $160.

Because a $160 oven is cheaper than a $161.50 oven, Shop B sells the oven at a lower price.

I hope this helps!
