<PRE><B>Question 304613</B>
It costs the student $693.00 to insure his car for the 4 months of summer. 
He spends $452.00 per month on gas. 
If the 4 months of summer and charges an average of $7.00 per fare, how many 
fares will he have to get to be able to pay his tuition of $3280.00? 
:
let x = no. of fares required to show a profit of $3280
:
7x - 4(452) - 693 = 3280
:
7x - 1808 - 693 = 3280
:
7x - 2501 = 3280
:
7x = 3280 + 2501
:
7x = 5781
x = {{{5781/7}}}
x ~ 826 fares</PRE>
