Answer:
44.81%
Step-by-step explanation:
First determine the z-scores for 3.5 and 5.5 years. After matching the z-scores with the areas under the standard normal curve, subtract the smaller area from the larger area to solve.
1 week=7 days
1/8- canned
rest- dry = 8/8-1/8= 7/8 (1 day)
1 treat (one day)
to find dry food, multiply 7/8 by 7
dry food in a day = 7/8 = 0.875 cup
0.875*7= 6.125 cups a week = 6 and 1/8 cups a week
-6
