Answer:
189.85
Step-by-step explanation:
Let X be the amount Juan pays for his tution.
Given that the current rate is 675/credit and Juan has 485.15/credit
#To get how much more he pays for his tution, we subtract the scholarship/ credit from the new tution fee/credit:
[tex]\bigtriangle x=Current \ Tution \ Cost - \ Scholarship\\=675/c-485.15/c\\\\=189.85/c[/tex]
Hence, Juan will pay 189.85 more per credit.
