a. Use rounding to estimate the number of cups. Explain or show your work. (3 points).
b. Calculate the exact number of cups. Explain or show your work. (3 points).
c. Based on the exact answer, is your estimate reasonable? Explain. (1 point).

Answer 1

a. about 47 cups
b. 49.3421053
c. (answer yourself) but to me, it is reasonable.

Answer 2

Why would you think is reasonable.

Answer 3

because if you rounded the .38 cents to 40, you would get 47 cups because there are less groups of 40 cents in 18.75 dollars. if you just did .38, which is what i did in the second part, you would get more groups of .38., 49. 47 is pretty close to 49.

Answer 4

I see how your doing that
