A.)
Financial Aid = $3,500 per year
Scholarship = [tex] \frac{1}{2} [/tex] of tuition
Word-study job = $5,300 per year
Tuition = $9,500 a year
Remember that scholarship pays for half of tuition so divide $9,500 by 2
9,500 ÷ 2 = $4,750
So now, it should be 3,500 + 4,750 + 5,300 which equals $13,550 a year from her "three" sources of income.
Technically, there are only 2 sources of income: financial aid and the work-study job since scholarships are only to be used for school, but let's not go there right now. I'll explain later in the comments if you ask.
B.)
$9,500 + $1,200 + $11,600 = $22,300 without the scholarship
$4,750 + $1,200 + $11,600 = $17,550 with the scholarship
C.)
$9,500 + $1,200 + $11,600 = $22,300
Sources of income: $3,500 + $4,750 (1/2 tuition off) + $5,300 = $13,550 income
$22,300 - $13,550 = $8,750
8,750 ÷ 22,300 = 0.39
0.39 x 100 (total percent) = 39%
100% - 39% = 61%
61% of her annual college costs are covered by her three sources of income.
D.)
$9,500 + $1,200 + $11,600 = $22,300 - total cost to go to the college
$3,500 + $5,300 + $4,750 = $13,550 income
$22,300 - $8,800 = $13,500
She has to borrow $13,500 each year.
