A car rental agency advertised renting a luxury, full-size car for $34.95 per day and $0.29 per mile. If you rent this car for 4 days, how many whole miles can you drive if you only have $200 to spend.
Let
y ------> total cost
x -----> number of miles
d -----> number of days
so
The linear equation that represents this situation is
y=34.95d+0.29x
For y=$200 and d=4
substitute
200=34.95(4)+0.29x
0.29x=200-34.95(4)
0.29x=60.2
x=207.59 miles
therefore
the answer is 208 miles
