At her job of grooming horses, Polly Yaskovich worked 8 hours a day on Monday and Tuesday earning $67 each day. On Wednesday, she earned $82. On Thursday, she earned $78. How much must Polly earn on Friday, to have average earnings of $75 a day?

Your answer is that she needs to earn $148 on Friday

Explanation:

Calculate Average:

(67 + 82 + 78) / 4 = 56.75    (Remember 67 is worth Monday and Tuesday)

We know that the number that the 4 numbers add up to has to be divisible by 5 because our we need to average 75 and we have 5 days to average on.

5 x 75 = 375

67 + 82 + 78 = 227

375 - 227 = 148

(67+82+78+148) / 5 = 75

Your answer is that she needs to earn $148 on Friday
