Question 260110
a Toyota for $21,700 with 47 mpg the second one is a Honda for $ 11,925 and 33 mpg.
 How many miles would you have to drive to make the two cars the same cost?
 gas per gallon is $3.15.
:
let m = no. of miles to make the cost equal
:
{{{3.15/47}}}m + 21700 = {{{3.15/33}}}m + 11925
To avoid some annoying fractions, will use decimals here
.06702m + 21700 = .09545m + 11925
:
21700 - 11925 = .09545m - .06702m
9775 = .02843m
m = {{{9775/.02843}}}
m ~ 343,800 mi to be equal, not exact because I used decimals
