Answer:
(a) The linear function that gives the total cost y to be paid by a student taking x credits is:
y = 170x + 140 (In Dollars)
(b) The cost of a student taking 15 credits is $2690
(c) If Bella could only afford to pay $1500 a semester, then the number of credits she could take is 8
Step-by-step explanation:
Given that a student is to pay tuition cost of $170 per credit and $140 student services fees.
(a) The linear function that gives the total cost y to be paid by a student taking x credits is:
y = 170x + 140 (In Dollars)
(b) The cost of a student taking 15 credits is:
y = 170(15) + 140
= 2250 + 140
= 2690 (in dollars)
(c) If Bella could only afford to pay $1500 a semester, then the number of credits she could take is:
1500 = 170x + 140
170x = 1500 - 140
170x = 1360
x = 1360/170
= 8
