Question

Kylee’s first three test scores are 81, 75, and 77. What must kylee score on the next test to raise the average to 80?

Answer 1

Answer:

Kylee must get an 87 on her next test to raise her average grade to 80.

Step-by-step explanation:

Her previous tests average: 81+75+77=233

233÷3=77.7

If she gets a 87 on her next test, it averages: 81+75+77+87=320

320÷4=80
