x + (30 * d) = 140

Where x represents the number of weekdays she practiced and d represents the number of weekdays in a week.

Let d represent the number of days it takes for the elephant to weigh a total of 224 pounds.

The elephant gains 2 pounds per day, so the weight after d days can be represented by the equation: 150 + 2d = 224.

To solve for d, we can subtract 150 from both sides of the equation:

2d = 224 - 150

2d = 74

Finally, we divide both sides by 2 to solve for d:

d = 74/2

d = 37

Therefore, it will take the elephant 37 days to weigh a total of 224 pounds.
