Answer 1

A bag contains 10 pounds of dog food.

A family feeds their dogs 0.85 pound of dog food a day so cin seven day the dog eats (0.85 x 7) = 5.95 pounds

so, dog food is left in the bag after 7 days is (10-5.95) = 4.05 pounds

Answer 2

Since there is .85 pounds of dog food fed to the dog everyday it saiz that how many are left in 7 days so our equation is 10-7(.85)=x
10-5.95=x
x=4.05
yet is says round it to the nearest pound so its 4 pounds
