.....Jeremy did not make a good inference. The ratio is not in proportion to 2/15. The correct inference would be about 26 students who did not read any books in July. The sample might be biased since it was limited to those at the pool....
The answer is 2,2
as 3*2 - 2 = 4
ans 2*2 +2 = 4
So it satisfies both eqautions
They sold 187 small bags and 75 large bags.
Two variables L and S (large & small)
We know that L + S = 262 -> the amount of bags sold
We also know that 3L + 1S = $412 -> total money made
L = 262 - S
Plug that into the second equation:
3(262 - S) + 1S = 412
786 - 3S + 1S = 412
786 - 2S = 412
786 - 412 = 2S
374 = 2S
S = 187
187 small bass and
So they sold 187 small bags
L = 262 - 187 = 75
They sold 75 large bags.
