Answer 1

The options for this question are missing. Here are the missing options:

A) -10

B) -9

C) -12

D) -13

Answer:

February - 29 days  (this means that it is a leap year)

Wrong av.given = 11 cups/day

So total = 319 cups

59 cups are total instead of 30 cups

So 319 - 59 = 260

260 + 30 = 290

New average  = 10 cups/day
