Question

Chris pays a fee if her bank balance falls below $10 on the statement date, her balance was -$3.46. Then, Chris made a deposit, d, in ample time, so she did not have to pay a fee. Write an inequality to represent this situation. Then solve the inequality. Describe the meaning of the solution.

Answer 1

Based on the information you provided, we can write an inequality to represent the situation. Chris's balance was -$3.46 and she made a deposit of d dollars. To avoid paying a fee, her balance must be greater than or equal to $10 on the statement date. So the inequality is: -3.46 + d >= 10. Solving for d, we get d >= 13.46. So Chris must have deposited at least $13.46 to avoid paying a fee.

Answer 2

If her balance is below 10, Chris must pay a few.

b = balance

Her balance was -$3.46. Then, Chris made a deposit, d, in ample time, so she did not have to pay a fee.

b + d > 10

b = -3.46

Inequality: -3.46 + d > 10

d > 10 - -3.46

Solved: d > 13.46

Meaning: The amount that Chris deposits has to increase her balance, so that it's not less than $10.
