Let x is the amount of money he borrows from his Friend, the interest from this amount is 5% x
x +200 is the amount of money he borrows from his Mom, the interest from this amount is 6% (x+200)
 10,000-(2x+200) is the amount of money he borrows from the bank, the interest from this amount is 7% (10,000-(2x+200)
total interest is = 624, solve for x and then solve for the amount of money he borrows from the bank
