Question

Nguyen wants to buy a tire that normally costs $86.25. It is currently on sale for $84 25. What is the percentage discount? Round your answer to the nearest tenth.​

Answer 1

• Cost price=86.25$
• Sale price=84.25$

• Discount=86.25-84.25=2$

Percentage discount

`\\ \rm\rightarrowtail (2)/(86.25){100}`

`\\ \rm\rightarrowtail 0.0232(100)`

`\\ \rm\rightarrowtail 2.32\%`

Answer 2

2.3% (nearest tenth)

Explanation:

`\sf percentage \ change =(|final \ value - initial \ value|)/(initial \ value) * 100\%`

Given:

• initial value = 86.25
• final value = 84.25

`\sf \implies percentage \ change =(|84.25-86.25|)/(86.25) * 100\%`

`\sf \implies percentage \ change =(2)/(86.25) * 100\%`

`\sf \implies percentage \ change =2.3\% \ (nearest \ tenth)`
