Heather made an 82% on her first test. What must she get on her next test to have an average of at least 90%? (assume 100 points per test). (This also has to be done algebraically).

There are two scores to average to 90 %

(82 + x )/2 = 90

82+x = 180

x = 98 She has to make at least 98 % on the second test.
