$145
to find the average divide earnings by 5
$725 ÷ 5 = $145
I'm just guessing because there isn't much data, but the ages could be:
1, 8, and 9
3, 3, and 8
1, 8, and 9
1, 6, and 12
2, 3, and 12
3, 4, and 6
2, 4, and 9
(These aren't all the possible ages)
true because the square root is a number times itself and 4*4 is 16
Move the decimal point 7 spaces to the right and it gives you 93,000,000
