Item 32 on three 150-point geography tests, you earned grades of 88%, 94%, and 90%. the final test is worth 250 points. what percent do you need on the final to earn 93% of the total points on all tests? !

97.2% on the final.
Find the total amount of points needed to get a 93%. 150+150+150+250 = 700 total points. 700*.93 = 651 total points needed to get 93%. find the points received from the other quizzes and subtract the sum from 651 to find how many points need to be scored on the final.
150*.88=132 (test 1)
150*.94=141 (test 2)
150*.90=135 (test 3)
132+141+135= 408

651-408 = 243 points to score on the final exam.
243/250 =.972 or 97.2%

Ithink the answer is: it is likely.
