Answer:

79+94+91+92+test5)/5=90

The lowest score have to be 94

Step-by-step explanation:

Our goal is gona be to have an average of 90, it can be higher but we are going to use this.

For average the equation is

(test1+test2+test3+test4+test5)/5=average

We know the result for the first 4 tests

Test 1=79

Test 2=94

Test 3=91

Test 4=92

But we dont know test 5

(79+94+91+92+test5)/5=average

Our goal for the average is 90

(79+94+91+92+test5)/5=90

79+94+91+92+test5=90*5

test5=450-79-94-91-92

Test5=94
