Question

koala
did you know? a koala, like all animals, is a consumer because it can’t make its own food like a plant does. a koala, however, is unusual because it consumes just one type of plant. a koala eats only the leaves and bark of a eucalyptus tree. in fact, a koala may eat up to 1,000 grams of leaves each day, and it may spend up to five hours a day eating!
1 a koala ate 495.32 grams of eucalyptus leaves on monday and 426.85 grams of leaves on tuesday. how much more did the koala eat on monday?
2 how many total grams of eucalyptus leaves did the koala eat on monday and tuesday?
3 every 10 days, a koala may eat an amount of eucalyptus leaves equal to its body mass. suppose the mass of a koala is 12.73 kilograms and it eats 11.58 kilograms of leaves during a 10 - day period. how much more was the mass of the koala than the mass of the leaves it ate?

Explanation:

Sub - Question 1

Step1: Identify the amounts eaten on each day

The koala ate 495.32 grams on Monday and 426.85 grams on Tuesday. To find how much more it ate on Monday, we subtract the amount eaten on Tuesday from the amount eaten on Monday.
$$495.32 - 426.85$$

Step2: Perform the subtraction

$$495.32-426.85 = 68.47$$

Step1: Identify the amounts eaten on each day

The koala ate 495.32 grams on Monday and 426.85 grams on Tuesday. To find the total amount eaten, we add the amounts eaten on Monday and Tuesday.
$$495.32+426.85$$

Step2: Perform the addition

$$495.32 + 426.85=922.17$$

Step1: Identify the masses

The mass of the koala is 12.73 kilograms and the mass of the leaves it ate is 11.58 kilograms. To find how much more the koala's mass is than the mass of the leaves, we subtract the mass of the leaves from the mass of the koala.
$$12.73 - 11.58$$

Step2: Perform the subtraction

$$12.73-11.58 = 1.15$$

Answer:

68.47 grams
