Question

Suppose you had d dollars in your checking account. You spent $20 but have at least $55 left. How much money did you have initially? Write, solve, and graph an inequality that represents this situation.

Answer 1

The solution would be d ≥ 75

Explanation:

To find this we know that we have at least 55, which can be modeled as:

d ≥ 55

And then we need to add 20

d ≥ 55 + 20

d ≥ 75

Answer 2

Explanation:

55-20 is less than or equal to (d)
