A toy car costing $50 is reduced by 10% in the sale. How much does it cost now? Show me your work plz

Answer 1

Answer:

Now it costs $45.

Step-by-step explanation:

I'll show you two different ways of doing it.

Method A. Find the dollar mount of the discount and subtract it from the original price.

The percent discount is 10%.

First, we find 10% of $50.

10% of $50 = 10% * $50 = 0.1 * $50 = $5

The dollar amount of discount is $5.

Now we subtract the dollar amount of the discount from the original price.

$50 - $5 = $45

Answer: Now it costs $45.

Method B. Find the percent of the discounted price and use it to find the discounted price.

The original price, $50, is 100% of the original price since 100% is the entire thing. The discount is 10%, so we subtract 10% from 100%.

100% - 10% = 90%

After you take off 10% from the original price, the discount price is only 90% of the original price. Now we find 90% of $50.

90% of $50 = = 90% * $50 = 0.9 * $50 = $45

Answer: Now it costs $45.

Answer 2

Answer:

$45

Step-by-step explanation:

divide 50 by 100 (as in 100%) then multiply it by 90 (as in 90%)

50 ÷ 100 × 90 = 45
