Answer:
$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
