13 points! : ) kerry bought a pair of athletic shoes for $45. she also bought a pair of colorful shoelaces for the shoes for $4. what percent of the total amount that kerry paid was the price of the shoelaces? round to the nearest tenth of a percent, if necessary.
a. 8.2%
b. 8.9%
c. 9.8%
d. 11.3%

Here in this case the answer is "a". The way to find the percentage is to add all the numbers you have which is $49. And then you need to use it to divide it with the percentage you need for the number. Which in this case you are searching for shoelaces and it $4. So you divide the cose of the shoelaces $4  to the total amount $49. And then you multiply by 100 to get the percentage. If you round it off the the tenth place you should get 8.2%
