21. The number who responded is 600 -150 = 450. Expressed as a fraction of the total, that is
450/600 = (150*3)/(150*4) = 3/4
22. Total fabric used is
6*(3 1/6) +8*(2 3/4) = 19 +22 = 41 . . . . yards
Fabric unused is . . .
50 yd -41 yd = 9 yd
23. The problem statement is ambiguous. We suppose it is intended to say that the stock increased by 1/4 of its original value. In that case, the present value is
$2000 +$2000*(1/4) = $2500
_____
An alternate interpretation of the statement is that the amount of increase was 1/4. In that case, the present value is
$2000 + 0.25 = $2000.25
Given that we have 47 kids and each kid needs 10 marbles, find out how many bags of 24 marbles will we need.
First, we will multiply 47 by 10 to get the amount of marbles needed.
47 x 10 = 470
So, that means we need 470 marbles in total.
Then, we divide 470 by 24 to see how many bags of 24 marbles 470 marbles is.
470 / 24 = 19.5833
Since, we can't have 19.5833 bags, we have to check what it would be if we only used 19.
19 x 24 = 456
470 - 456 = 14
Since, 18 is the closest number of bags but it has less than 470 it would not be correct.
Therefore, the best answer would be B. 25 since it is better to have extra marbles but not a very wide margin.
