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?

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
