Answer:
72
Step-by-step explanation:
mean=average. to get average, you add up the numbers and divide by how many numbers. they add upp to 288 and since theres 4 test grades, divide by 4 to get 72.
Since the tax is 6.25%, make it into a decimal which is .0625 then multiply by 600 to get 37.5, then add it to the 600 and the answer is .... $637.5 Yw (:
