A standard airline jet has 25,812 gallons of fuel and burns 4.2 gallons per mile. A jumbo airline jet has 31,311 gallons of fuel and burns 5.5 gallons of fuel per mile. How many miles (d) must each jet travel so they both have the same amount of fuel remaining? Step 1: Choose the general equation for this situation.

1. distance traveled by a standard airline jet = distance traveled by a jumbo airline jet
2. rate fuel is burned with a standard airline jet = rate fuel is burned with a jumbo airline jet
3. amount of fuel in a standard airline jet = amount of fuel in a jumbo airline jet
4. rate fuel is burned with a standard airline jet rate fuel is burned with a jumbo airline jet

32.10 is the correct answer

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
