Question

The zoo has a pride of 8 adult lions and 3 cubs. The adults eat 5 pounds of meat each day and the cubs eat 3 pounds of meat each day. How many pounds of meat is consumed by the lions each day? Write and evaluate the expression to show how much meat the lions eat per day.

Answer 1

Each adult lion eats 5 pounds of meat per day

There are 8 adult lions.

So, total they eat:

8 * 5 = 40 pounds per day

Now,

the cubs eat 3 pounds of meat per day

There are 3 cubs.

So, total they eat:

3 * 3 = 9 pounds per day

Full Total amount of meat per day for all lions is:

40 + 9

= 49 pounds of meat per day

----------------------------------------------------------------------------------------------------------------

If we were to write an expression of total amount of meat neede per day, we could write:

8x + 3y

Where

x is the amount of meat adult lion eats per day and y is amount of meat cubs eat per day

We know adult lion eats 5 lb per day and cubs eat 3 lb per day,.

So, we would evaluate the expression for x = 5 and y = 3

We would get:

8x + 3y

8(5) + 3(3)

40 + 9

= 49
