Asked by Tiffany Johnson

Im not sure the formula for this- John bought 200 yards of paper for $1.95. Jack needs 40 yards of paper how much will it cost Jack for the paper ?
Answered by Damon
40 yards *(1.95 dollars / yard) = ? dollars
Answered by Damon
Whoops, excuse me. I forgot John bought 200 yards.

40 yards *(1.95 dollars / 200 yards) = ? dollars

I don't interpret this question the same as Damon. I interpret it to mean John bought 200 yards of paper for 1.95 (TOTAL) which makes the cost per yard of $1.95/200 yards = $0.00975/yard.
Then Jack must pay, provided the cost is the same;i.e., no discount for larger amounts, 0.00975/yard x 40 yards = ??

Set it up like a proportion
200 yds 40 yds
------- = ------
$1.95 x

Mutiply top to bottom then divide by your other number

1.95 x 40 = 78
then 78 divided by 200 = $ .39
