Can someone help me with this?

Question

Brian rented a truck for one day. There was a base fee of $17.99 , and there was an additional charge of 75 cents for each mile driven. Brian had to pay $157.49 when he returned the truck. For how many miles did he drive the truck?

Answer 1

Subtract the base fee, $17.99, from total fee. $157.49-$17.99. Then divide that result by . 75. This will give you the number of miles driven. 

Answer 2

So basically this is a simple setting up an equation problem.

$17.99 + $0.75x = $157.49

 

where x is the amount of miles driven, 

and the base fee is added to the amount of miles times the cost per mile, which equals the total. 

 

then you just solve for x by subtracting $17.99 from both sides, then dividing both sides by $0.75 to get your x-value. 

Hope this helped!
