Answer:
The correct answer is $138.
Explanation:
We must start by analyzing the information they have given us.
We know there is a pair of sneakers that costs $ 120.
But at the time of paying, they add an increase to that price of 15%.
To know the final price of sneakers we must know what is the value of that 15% applied.
And one of the ways to do that calculation is to multiply the value of sneakers by 0.15:
120.0,15 = 18
Now we know that the sneakers have increased $ 18, which we will add to the original price to get the total value of the sneakers:
18 + 120 = 138.
Therefore the correct answer is $ 138.
