1) If y is the amount of dog food in the bin, and x is the number of days the dogs have been fed, write an equation to represent the amount of food left in the old dog’s bin.

You are pet sitting your neighbor’s dogs for a couple of weeks. Each dog must be fed a different type of food. The instructions say to feed the old dog 2/3 pound of food each day from the bin with 25 lbs of kibble in it. The puppy is to get 1/4 pound of food each day from the bag with 20 lbs of puppy kibble in it. Use your system of equations to calculate the number of days until both containers have the same weight of food in them.

2)If y is the amount of dog food in the bin, and x is the number of days the dogs have been fed, write an equation to represent the amount of food left in the puppy’s bin.

3)Use your equations to solve to find the number of days when both containers will have the same weight of food in them. (check your solution!)

2. The equation computed shows that the number of days until both containers have the same weight of food in them will be 12 days.

### How to calculate the equations?

From the information given, the instructions say to feed the old dog 2/3 pound of food each day from the bin with 25 lbs of kibble in it. the equation will be:
= 25 + 2/3d
= 25 + 0.67d
Also, the puppy is to get 1/4 pound of food each day from the bag with 20 lbs of puppy kibble in it. This will be:
= 20 + 1/4d
= 20 + 0.25d
The number of days until both containers have the same weight of food in them will be:
25 + 0.67d = 20 + 0.25d
0.67d – 0.25d = 20 – 25
0.42d = 5
d = 5/0.42
d = 11.9
d = 12 days
