Question

In August, Ralph bought a new set of golf clubs that cost $565. The cost of the clubs was marked up to $650 in October. Which proportion can be used to find what percent of the original price the new price is, if p represents the unknown percent?

Answer 1

565/650=p/100

Explanation:

565 has to multiply by 100 to get the right answer so if you cross multiply its right.

Answer 2

The percent of the original price, the new price is given as 86.9%

Solution:

Given, In August, Ralph bought a new set of golf clubs that cost $565.

The cost of the clubs was marked up to $650 in October.

We have to find which proportion can be used to find what percent of the original price the new price is, if p represents the unknown percent?

The formula is normally partial/whole equals to percentage/100. In this case $565 is partial because the price increased.

So it will be,

`(565)/(650)=(p)/(100)`

`\begin{array}{l}{565 * 100=p * 650} \\\\ {650 p=56500} \\\\ {p=(56500)/(650)=86.9230}\end{array}`

Whenever you get results like these, you just need to round to the nearest hundredths place, which is 86.9%.

Hence, the percentage is 86.9%
