Answer 1

Answer:

A. $0.43

B. 480 ounces

C. $0.03

D. 12.25 ounces

E. 39 days (39.18 days)

F. $0.37

Step-by-step explanation:

A.

30 pounds cost 12.95, so 1 pound would cost 12.95 divided by 30.

$\frac{12.95}{30}=0.43$

1 pound cost $0.43

B.

There are 16 ounces in 1 pound. So the bag, which weights 30 pounds, would have 16 multiplied by 30 ounces.

$16*30 =480$

The bag has 480 ounces

C.

since 480 ounce cost 12.95, to get each ounce cost, we need to divide 12.95 by 480:

$\frac{12.95}{480}=0.03$

Each ounce cost about $0.03

D.

The dog eats 3.5 cups per day with each cup weighing in at 3.5 ounces. So the dog eats 3.5 * 3.5 = 12.25 ounces

the dog eats 12.25 ounces of dog food each day

E.

Since there are 480 ounces in total in the bag and dog eats 12.25 ounces per day, to get the number of days it will take the bag to empty, we need to divide 480 by 12.25:

$\frac{480}{12.25}=39.18$

The bag would last a little more than 39 days

F.

We figured the cost per ounce to be $0.03 and dog eats 12.25 ounces per day. To get cost per day, we need to multiply these 2 numbers:

$0.03*12.25=0.37$

The cost per day is $0.37
