Answer:$17,260 is how much more he will have to earn to pay for his degree!
Step-by-step explanation:First you have to multiply 7,215 with 4 and you get 28,860.Next you multiply 1,350 by 4 and you get 5,400.Then you add 5,400+4,200+2,000 and you get 11,600.Last but not least,you subtract 11,600 with 28,860 and you get $17,260!
That would be -20. a negative divided by a negative number is positive, positive divided by negative is negative bc even numbers of negatives make it positive. and ofc 20 x 5 = 100, hence the ‘20’
