Question

In this third section, you’ll use equations, inequalities, and geometric reasoning.

Your daily revenue was $50 at the start of the month, and it increased by $0.85 each day.

The inequality 50 + 0.85x ≥ 74.65 represents the number of days, x, until your daily revenue reaches at least $74.65.

Which inequality represents the number of days, x, until your revenue reaches at least $74.65?
Question 13 options:

x ≥ 147

x ≤ 29

x ≥ 29

x ≤ 147

Answer 1

Start with 50 + 0.85x ≥ 74.65. Subtract 50: 0.85x ≥ 24.65. Divide by 0.85 (positive), x ≥ 24.65/0.85 = 29.

So the correct choice is: x ≥ 29.
