Answer 1

so we have to add the expenses and savings, and subtract them afterwards, lets call them negative and positive respectively to group them:
negative = tuition + room + book + personal
negative = 7800 + 6725 + 1200 + 2225
negative = 17950

positive = savings + grant + scolarship
positive = 5685 + 1500 + 3750
positive = 10935

we have to subtract the negative from the positive to have a grand total:
total = positive - negative = 10935 - 17950= -7015
that means that the savings, grant and scholarship are not enough to pay the total expenses, they lack $7015 indeed
