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

Lets use the letter C to represent cats and D to represent dogs.
A) 2.35c + 5.50d = 89.50
For B, they give you numbers to plug into your equation.
c = 8
d= 14
B) 2.35(8) + 5.50(14) = 89.50
18.80 + 77.00 = 95.80
So what Pat said is incorrect because that would mean they spent more than 89.50.
Hope this helps! :)
Even though the money is required 2 years from now, the first deposit is made only a year from now, therefore in the bank for only one year.
The second deposit will be in the bank the same day it will be taken out, so no interest whatsoever.
Thus future value
= 8200(1.062)+8200
=$16908.40
will be available assuming compounding annually.
