Suppose you had d dollars in your bank account. You spent $21 but have at least $53 left. How much money did you have initially? Write and solve an inequality that represents this situation.

1 answer

Let's denote the initial amount of money you had in your bank account as x.
You spent $21, so your bank account is now x - 21.
You have at least $53 left, so we can write the inequality as:
x - 21 ≥ 53

To find the initial amount of money you had in your bank account, we solve for x:
x - 21 ≥ 53
x ≥ 53 + 21
x ≥ 74

Therefore, you initially had at least $74 in your bank account.
