A certain kind of animal weighs about 71 pounds at birth and gains about 2 pounds per day for the first few weeks. Determine those days for which the animal's weighs more than 117 pounds.

The animal's weight is more than 117 pounds when the animal is more than__ days old.

I said 89 days old

How can he be 89 days old when he's only gained 46 pounds?

He would be 23 days old. If he has only gained 46 pounds. Right?

A certain kind of animal weighs about 71 pounds at birth and gains about 2 pounds per day for the first few weeks determine those days for which the animals weight is more than 117 pounds

To determine the number of days for which the animal's weight is more than 117 pounds, we can set up an inequality based on the information provided.

Let's denote the number of days since birth as "d" and the animal's weight on that day as "W".

Given that the animal weighs about 71 pounds at birth and gains about 2 pounds per day for the first few weeks, we can express the animal's weight as:

W = 71 + 2d

To find the days for which the animal's weight is more than 117 pounds, we need to solve the inequality:

W > 117

Substituting the expression for W from above, we get:

71 + 2d > 117

Now, let's solve this inequality for d:

2d > 117 - 71

2d > 46

d > 46 / 2

d > 23

Therefore, the animal's weight is more than 117 pounds when the animal is more than 23 days old, not 89 days old as you mentioned.
