Tony ran laps around a track to raise money for a hospital. Tony raised $15 plus $1.50 per lap that he ran. He raised a total of $255.

Let x represent the number of laps Tony ran.

What expression completes the equation to determine the total number of laps Tony ran?
How many laps did Tony run?

Enter your answers in the boxes.

Answer 1

He ran a total of (((((((((  160 LAPS  ))))))))))) because if you subtract $15 from $255 it equals $240 then you wanna divide that by $1.50 and it equals 160 laps you get it ?

Answer 2

Answer:

Tony ran 160 laps.

Step-by-step explanation:

We know Tony raised $255 total, we can subtract the $15 he raised because that has nothing to do with the number of laps he ran. We are left with $240, if Tony gets $1.50 per lap we can divide $240 by $1.50.

240/1.50= 160

our equation: 255=15+1.50x

again, we are trying to isolate x so we can solve this by subtracting 15 from each side to get 240=1.50 now we divide to detach the 1.50 from x.

Dividing from both sides get us 160=x, let's check our work by plugging 160 into the equation.

255=15+1.50(160)

255=15+240

255=255

so, this proves Tony did 160 laps.
