A dog shelter recorded the number of dogs, d, in their care as well as the pounds of dog food, f, the dogs consumed in a day. The table represents the relationship between the number of dogs, d, and the amount of
food they ate, f. Name the independent variable and the dependent variable and explain.
Dogs 10 15 20 25 30
Food (lbs) 20 30 40 50 60

5. Use the table in question 4 to write an equation using d and f to illustrate the relationship between the two
variables. Be sure to write the dependent variable in terms of the independent variable.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
