The cost of a taxi is $3 plus $0.75 for each mile traveled. If a taxi fare is $7.50, which equation could be used to find *m*, the number of miles traveled?

(3 + 0.75)*m *= 7.50

3 + 75 *m* = 7.50

3 + 0.75*m* = 7.50

7.50 + 3 = 0.75*m*

$3.00 is a fixed amount; it's only paid once so it should stand all by itself and not be multiplied by anyhing.

Therefore the first equation should be eliminated.

The total fare is $7.50 so this is what the equation equals. Therefore, the fourth equation should be eliminated.

We're dealing with $3.00 and $0.75; so we need an equation which has 3 and 0.75; this is equation three.

Equation two is eliminated since the 75 has no decimal point in front of it, so it means $75.00.
