Thank you for watching the video through, I used the 1/3 to represent the fraction of the tank already filled, I defined the variable as a real world number. From there, if 1/3 is filled and the tank capacity is 15, that means there is currently 5 gallons of gas in the tank (1/3*15=5). If there is 5 gallons of gas in a 15 gallon tank, then you need to pump in 10 gallons of gas to fill the tank (5+10=15). So according to this, we can define f as 1/3 and g as 10, substitute them into the equations given in the answer choices, and find which one is true.
for the first question why did you assume 2 for the ticket price
can you do more advanced relationships word problems?
Sure, thanks for the suggestion
hi, can u explaine the 1/3 of 15 is 5 and then where did the 10 come from. i didn't get that part.
Those vidoes are so helpfull, thank u!
yes omg
