Question 907244
.79x + .69(x+2) = 16.18
NOTE: I'm assuming that your question should read 'dog' then 'cat' instead of both dog.
Distribute
.79x + .69x + 1.38 = 16.18
Subtract 1.38 from each side
1.48x = 14.8
Divide each side by 1.48
x = 10 cans of dog food
If 10 cans of dog food, then 12 cans of cat food
10 * .79 = $7.90
12 * .69 = $8.28
$7.90 + $8.28 = $16.18
