Eliana drove her car 81 km and used 9 liters of fuel. She wants to know how many kilometers (2) she can drive on 22 liters of fuel. She assumes her car will continue consuming fuel at the same rate.
As:
How far can Eliana drive on 22 liters of fuel?

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
