Mercedes would like to have an average of 88 in her math class. There are five assignments with the following grades : 85, 100, 88, 80, 95. What grade will Mercedes need to make on the last assignment to meet her goal.

80%

Step-by-step explanation:

To find the average, add all the grades and divide by the number of grades

sum of all grades/number of grades

85 + 100 + 88 + 80 + 95 + x/6

She wants to have an 88, so we can set the expression above equal to 88

448 + x/6= 88

Multiply by 6 on both sides

448 + x = 528

Subtract 448 on both sides

x=80

She needs to score at least an 80 to get an 88 average.

Hope this helped!

answer: 100
