A shirt purchased for $20. The store owner will sell it for a 40% mark up. What will the new price be?

$28

Step-by-step explanation:

So we know the shirt is $20, and the owner is raising the price by 40%. That means we are adding $20 to 40% of the cost of the shirt

$20 + 40%

So we have to figure out how much 40% of $20 is. To do that, you can use fraction or decimal type

40% is the same thing as 40/100 or 0.4.  So you will multiply either of them by $20 to find how much 40% of $20 is.

40/100 * 20 = 8

0.4 * 20 = 8

Now we know that 40% of $20 is $8. So now we will add 8$ to $20

20 + 8 = 28

The new price will be $28
