Step-by-step explanation:
First let’s find out what he owes per year. That’s tuition plus boarding costs minus the scholarship: 43,800 + 4132 = 47, 932.
From this we subtract the scholarship (8000) and the amount his grandma will put in (5,000) for the freshman year. 47,932 - 13,000 = 34,932
His parents saved 84,000 But are splitting it evenly over four years so that’s 84,000 / 4 = 21,000 per year.
So for his freshman year that’s 34,932- 21,000 = 13,932 that he has left to pay.
His remaining balance is 13,932
