Not sure if I'm right but I believe they intersect at (1,4).
Answer:
Step-by-step explanation:
To find how far she can walk in 3 minutes, we need to find how fast she can walk in 1 minutes. We do this by dividing the distance she walked by the time she walked. Lets do so.
3200/24=133.33
She walks 133.33 meters per minute. Now to find her distance in 3 minutes w multiply this number by 3.
133.33*3=400
Barbra walks 400 meters every 3 minutes.
You multiple everything in the ( )’s with the number outside of the ( )’s
54+x=12+3x
X=21 =number of classes
Total amount she will pay is $75
