A worker at the zoo calculates the amount of fish, in pounds, needed in the weekly diet of an eagle and a bear.

·The eagle eats 6 pounds of food each week, and 60% of that weight must be fish.
·The bear eats 105 pounds of food each week, and 25% of that weight must be fish.

PART A
What is the total number of fish, in pounds, that the eagle and bear should eat each week? Round your answer to the nearest hundredth of a pound.

PART B
The zoo increases the amount of food that the bear eats each week to 115 pounds. What is the percent increase in the amount of food that the bear eats each week? Round your answer to the nearest tenth of a percent.

Answer :

Part A

60% of 6=3.6 lbs of fish for the eagle
25% of 105=26.25 lbs of fish for the bear

3.6+26.25=29.85 lbs of fish combined

Part B

25% of 115= 28.75 lbs

Percent increase= (new-old)/old x 100%

(28.75-26.25)/26.25 x 100% = 9.52

9.52% increase
