Answer: 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!
Prime factorization means that we divide 90 by prime numbers only.
90 ÷ 2 = 45
45 ÷ 3 = 15
15 ÷ 3 = 5
2 x 3 x 3 x 5 = 90
2 x 3² x 5 = 90
or 2,3,3,or 5
