Answer:
Kalino would need to earn at least a 97 on his fifth test.
Step-by-step explanation:
The average is calculated by adding up the amounts earned on each test and dividing by the total number of tests. In this case, the score for the last test is not known, but the expected average of 90 points is, so we can set up an equation to solve for the unknown test value:
'x' represents the score of the fifth test. Using inverse (opposite) operations and doing the same operation to both sides of the equation, we can first multiply both sides by 5:
x 5 = 90 x 5
353 + x = 450, now subtract 353 from both sides: 353 -353 + x = 450 - 353
x = 97
