Question

My closest friend seven dollars he got his weekly allowance of $20 he paid back his friend and download it a nine dollar album how much money does he have left

Answer 1

assuming the poor grammar you mean he owed his friend 7$, bought a 9$ album with his 20$ allowance.

9 + 7 = 16

20 - 16 = 4

he's got $4.00 left.
