Fred is closing a bank account t and wants to distribute the money among his grandchildren by giving each of them \$20. To do this Fred needs an additional \$62 . Instead he gave each grandchild \$17 and had \$7 left over. How many grandchildren does Fred have? How much money did he have in the bank account?

• Math -

let the number of grandchildren he has be n

so total money = 17n + 7

20n = 17n+7 + 62
3n = 69
n = 23

total money = 17(23)+7 = \$ 398
And he has 23 grandkids

check:
if he wanted to give each \$20,
he would need \$ 460,
But he has only 398, which is \$ 62 short of what he needs.

He has 23 grandchildren, WOW
