Question

It takes Dave's dogs about 20 days to finish a 50-pound bag bag of dog food. which is the best estimate of number of pounds of dog food Dave's dogs eat in one year
A)400
B)750
C)900
D)150

Answer 1

The correct answer is C) 900

To begin with, you need to divide the number of days in a year with the number of dogs. When you do this, you multiply it by 50 to get the final answer. In this case, it would be 365 / 20 which when multiplied by 50 gives the number of C) 900 since it's "about" 20 days.
