a baby elephat weighs 150 ponds when born it gain it gain 2 pounds per day during the first year

To find out how much a baby elephant weighs after a certain number of days, you can use the formula:

Weight = Initial weight + (Weight gain per day * Number of days)

In this case, the initial weight is 150 pounds and the weight gain per day is 2 pounds.

Let's say we want to calculate the weight after 100 days:

Weight = 150 + (2 * 100)
Weight = 150 + 200
Weight = 350 pounds

After 100 days, the baby elephant would weigh 350 pounds.
