a. $5,925
b. $7,650
c. $11,850
d. $15,300

the answer is defiantly B

The correct answer is option B,  $7,650

Step-by-step explanation:

There are two semesters in a year.  

Marco’s total expense for one year in a college = $18,750

Out of this, expenses met by annual grants = $3,450

Remaining money to be arranged by Marco = $18,750 - $3,450

= $ 15300  

This $ 15300 is the money require to be arranged for one year

Since there are two semesters in a year , money to be arranged per semester  

= $ 15300/2  

= $ 7650

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
