You need to know the difference between seven 11gal buckets, and seven 8gal buckets.

but that sounds like a lot of math, lets make it simpler.
bearing in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient


quick note:
the "x" must not have a negative coefficient for the standard form, though in this case it shows like so in the inappropriate choices above.
Okay, so, Colby made 9 batches, right? And each batch contained 1/4 quart of grape juice. To find how much grape juice he used for the 9 batches, you have to multiply 1/4 and 9.
1/4*9 = 9/4.
Simplified: 9/4 turns into 2 1/4.
Colby used 2 1/4 quarts of grape juice.
Answer:
101
Step-by-step explanation:
If you add up all of the answers, it equals 101 due to the fact of just adding all of the x's together in a row.
