Soda Vendor
Problem

l+s=1000
.7l+.5s=580
.7l+.5(1000-l)=580
.7l+500-.5l=580
.2l=80
l=400
s=1000-l=600
check
.7*400+.5*600=280+300=580

check
5n/6+7=5*42/6+7=5*7+7=35+7=42

400 x .70 and 600 x .50
Since 1,000 at .50 would be only $500. take the extra $80. and divide them by the difference of the .50 and .70 or 80/.20
That will give you the number of .70 sodas he sold.
Take that number off 1,000 and you have the number of .50 sodas sold.

1) x = large sodas, y = small sodas. x + y = 1000, .7x + .5y = 580. Solve for either.
2) A B C D E F G H I
A B C D F G H I
B C D F G H I
B C D F H I
B C F H I
B F H I
B H I
B H
H
He should be H.
3) Let x be the # of cats: x = 5/6 * x + 7. Solve for x.
