What is 4 feet, 1 inch minus 2 feet, 11 inches?
a. 1 ft, 9 in
b. 2 ft, 2 in
c. 1 ft, 2 in
d. 2 ft, 4 in

I think the easiest way to approach this is to first convert them into inches. There are 12 inches in 1 foot, so the first value will be 49 inches and the second value is 35 inches. Subtract 49-35 which is 14 inches. Convert back to feet and you will get 1 foot 2 inches.

It is 198,87032,750 + 375 = 33145 so, we take the 6% and we make it a decimal (0.6) and multiply that, then that is your answer
