suppose that you get in a taxi and you see the following fare schedule is $2.30 plus $0.50 per mile how much will you pay to go 10 miles
.50 X 10 + 2.30 you can do the math
if my math is correct it would be $29.00
easy: c=cost; f=fare; p=per mile cost($0.50); x=# of miles. c=px+f. c=0.5*10+2.3= $7.30. I believe my math is right.
