When Sal rented a car for 3 days, he drove it a total of 90 miles and paid $193.35. When Ashley rented a car for 5 days and drove it a total of 125 miles, she paid $318.50. If the car rental company charges a fee per day and a rate per mile, what is the fee per day to rent a car?

i think the equation here would be a system of equation the equations are
3x + 90y = 193.35 and 5x + 125y = 318.50

you can use creamer's rule.

C= 3  90
     5  125

C=-75

x= 193.35    90
      318.50   125
divided by value of C

x=59.95

y= 3   193.35
     5    318.50
divided by value of C

y= 0.15

the question only ask the fee per day so your answer will be the value of x only
