It’s A. 10 feet is 10/3 yards and if you multiply that by 4 you get 40/3. Simplify the fraction and you get 13 1/3
I believe the answer is 120. 3 5/6 turns into 3.833 when turned into a decimal. 3.833 would round up to 4 which is the nearest whole number. 34 3/7 would turn into 34.4285 as a decimal which turns into 30 when rounded to the nearest ten.
40 bikes. 120 times 40 equals 4800 divided by 2 because they pay for half the bike will be 2400
