Answer 1

To determine the number of days it will take for Will to have a balance of at least $0, set up an inequality and solve for x. It will take at least 22 days.

Step-by-step explanation:

In order to determine how many days it will take for Will to have a balance of at least $0, we need to set up an inequality.

Let x represent the number of days. We know that Will saves $2.50 per day, and he currently has -$55.00. So, the inequality will be: -55 + 2.50x ≥ 0.

To solve this inequality, we need to isolate the variable x. First, we need to add 55 to both sides of the inequality: -55 + 55 + 2.50x ≥ 0 + 55. This simplifies to: 2.50x ≥ 55.

Next, we divide both sides of the inequality by 2.50 to solve for x: (2.50x) / 2.50 ≥ 55 / 2.50. This simplifies to: x ≥ 22.

Therefore, it will take at least 22 days for Will to have a balance of at least $0.

Answer 2

It will take will 20 days to have a balance of $0
