Question

a student uses his car as a taxu..it costs the student $693.00 to insure his car for the 4months he drove as a taxi driver. he spends $452 per month on gas. if he lives with his parents and has no other expenses for those 4 months and charges an average of 7.00 per fare, how many fares will he have to get to be able to pay his expenses and his tuition of $3280?

Answer 1

452 per month

in 4 months he needs 452*4 = 1808.

total costs: 693+1808+3280 = 5781

5781 /7= 825. 85

so he needs a minimum 826 fares.  

Answer 2

How about showing the work on this one

Total expenses = insurance + gas + tuition

=693 + 452 *4 + 3,280

=5,781

Fares = total expenses/per fare charge

=5,781/7

=825.857

So you need 826 fares to cover it all

Answer 3

826 minimum

Answer 4

452 x 4 =1808 (because it is for 4 months)

693 you dont multiply because it is this amount for the 4 months

so...

1808+693+3280= 5781

5781/7 divided by 7 = 825.86.

Rounded up 826
