Question

a barrel contains 101 gallons of water and is being drained at a contant rate of 8 gallons per minutes.
write an equation that models the number of gallons.g after t minutes.
the equation that models the given situation is____.

Answer 1

In 1 minute, the barrel loses 8 gallons = 8 * 1 gallons
In 2 minutes, the barrel loses 16 gallons = 8 * 2 gallons
In 3 minutes, the barrel loses 24 gallons = 8 * 3 gallons
In t minutes, the barrel loses 8t gallons

Answer 2

The barrel started with 101 gallons, so the equation has to show that 8t gallons are being taken away from 101 gallons.
Can you come up with the equation?

Answer 4

If you have $101 and $8 is taken away, how would you show that. I don't mean the result. I mean which operation would you use to show $101 take away $8?

Answer 5

101-8

Answer 6

93

Answer 7

ok im lost

Answer 8

Right, $101 take away $8 is $101 - $8

In this case, they want an equation in which you show the full barrel, 101 gallons, and then you take away 8t gallons, so it is:

101 - 8t

They also say the number of gallons is represented by the letter g, so the answer is

g = 101 - 8t
