Best ResponseYou've already chosen the best response.0Let x = cost of a bag of cat litter and y=cost of a can of food. The first sentence implies \[3x+21y=42\]The second sentence implies\[4x+32y=60\] Solve the first equation for y in terms of x and plug that expression into the second equation for y. Then rearrange and solve for x.
