Answer:
n ≥ 29
She needs to do more than 29 pushups on the sixth day.
Explanation:
First, we need to use the formula for finding the average. We currently have numbers for the first 5 days.
(22+26+21+25+27+n)/6 = 25
Multiply both sides by 6.
25*6 = 150
150-27-25-21-26-22=x
x=29
Since it is an inequality, Sarah needs to do more than 29 pushups on the sixth day.
