A rain barrel is full of water and used to water a garden. The rain barrel loses water at the rate of 2.5

gallons of water per minute. After seven minutes, the rain barrel contains 37.5 gallons.

1. How many gallons of water were initially in the rain barrel? Show or explain your work.

2. Write an equation in point â€" slope form to model the number of gallons (y) of water in the rain

barrel after (x) minutes. Show or Explain your work.

3. If the Rain Barrel was full of water, how many minutes does it take for the rain barrel to drain so it

contains 25 gallons of water? Show or explain your work.

4. What is the total number of minutes it will take to completely empty the rain barrel? Show or

Explain your work

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
