Question

Santa has a leak in Santa's fuel tank. Santa lost three gallons last week and five gallons this week. What number should Santa add to the amount Santa started with to find what Santa has left? (Hint: Santa will be adding a negative number.)

Answer 1

According to the problem, consider the following amounts:

fuel leak last week = 3 gallons.

fuel leak this week = 5 gallons

then, the total fuel leak is 3 gallons + 5 gallons = 8 gallons.

Now, according to the hint given in the problem (Santa will add a negative number), we can say that the number Santa must add to the amount of fuel he started with to find the remaining fuel is:

- 8

So that, the correct answer is:

- 8
