She will have to pay $2,700.
She is starting with a bill of $11,000. If we subtract the 1500 grant and 5000 scholarship, she has left a bill of 4500.
She is going to earn 40% of it, so she still have to pay 60% of it.
0.6 x 4500 = 2700
Y=13
(when you have fractions like the one in this problem, you get rid of them by multiplying both sides by the denominator.)
simplify
n-2 = 10n/2 + 4/2
n-2 = 5n + 2
subtract 5n to both sides
n - 2 - 5n = 5n + 2 - 5n
simplify
-4n - 2 = 2
add 2 to both sides
-4n - 2 + 2 = 2 + 2
simplify
-4n = 4
divide both sides by -4
-4n/-4 = 4/-4
simplify
n = -1
hope it helps
