Question

The cost pair of inline skates is $63. If the inline skates are on sale for 35% off, what is the sale price of the inline skates in dollars?

Answer 1

See a solution process below:

Explanation:

The formula for solving this problem is:

`p = c - (c * s)`

Where:

`p` is the price of the item after the sale percent is removed. What we are solving for with this problem.

`c` is the original cost of the item. $63 for this problem.

`s` is the sales rate - 35% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 35% can be written as `35/100`.

Substituting and calculating `p` gives:

`p = $63 - ($63 * 35/100)`

`p = $63 - ($2205)/100`

`p = $63 - $22.05`

`p = $40.95`

The sale price of the inline skaters is $40.95

Answer 2

`$40.95`

Explanation:

One way of finding the sale price is to find the percent discount and subtract it.

`35% " of "$63` is:

`35/100 xx 63`

`= $22.05`

So if the price is reduced by `$22.05`, the amount to be paid is:

`$63 - $22.05 = $40.95`

Another way is to realise that if the price is being reduced by `35%`, then only $`$65%` is being paid:

`100% -35% = 65%`

Find the remaining `65%`

`65% " of " $63`

`=65/100 xx $63`

`= $40.95`
