Set up a ratio of known to unknown:
Let X = the amount of gas needed for 500 miles:
220/12 = 500/x
Cross multiply:
220x = 6000
Divide both sides by 220:
X = 6000 / 220
x = 27.27 gallons (round answer as needed).
I belive it would be y=-5/1x+6?
But im only like 90% sure so dont take my word for it but i hope that right?
For this case we have that the total minutes spent in yoga classes last week was 165.
Subtracting the 45 minutes of the Saturday day we have:

So, 4 week yoga classes were held
ANswer:
