Ed has a water container that holds 3 gallons of water. Ed used water from a full container to fill four bottles that each hold 8 ounces and a pitcher that holds 1 quart. How many ounces of water are left in the water container?

= 324 ounces left over from 384 ounces

1 quart is 32 and 8 x 4 = 32     We add them together; 32+ 32= 64 ounces then convert 3 gallons to ounces = 384

We subtract;  

384-64=324 ounces.

We convert again 128 p/g + 128p/g = 256 ounces = 2 gallons

We subtract; 324-256 = 68

We divide;

364/68 =91/17 = 5 +  6/17 = < 1/6

364/64 =90/14 = 5 + 7/10  = < 1/6

64= < 1/5 of 384 ounces

324 = < 384 ounces

2 gallons, plus 17/32 units of a gallon. = exact =324 ounces.

as 68/128  = 128/68 = /4 each  = 17/32

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
