32. A bank offers two debit cards. The basic card has a monthly fee and offers no cash back. The premium card has a monthly fee of $25, but offers 2.4% cash back on all purchases. At a minimum, how much would one month’s spending have to be for the cashback card to be the better choice? Round to the nearest dollar.
1. **State the problem:** We need to find the minimum monthly spending $x$ such that the premium card with a $25$ monthly fee and $2.4\%$ cash back is better than the basic card with a monthly fee but no cash back.
2. **Set up the inequality:** Let $x$ be the monthly spending amount.
Cost of basic card = monthly fee (unknown, but since we want the premium to be better, we compare the net cost difference)
Cost of premium card = $25 - 0.024x$
We want the premium card to be better, so:
$$25 - 0.024x < 0$$
3. **Solve the inequality:**
$$25 < 0.024x$$
Divide both sides by $0.024$:
$$\frac{25}{\cancel{0.024}} > \frac{0.024x}{\cancel{0.024}}$$
$$x > \frac{25}{0.024}$$
4. **Calculate the value:**
$$x > 1041.666\ldots$$
5. **Round to the nearest dollar:**
$$x > 1042$$
**Answer:** The monthly spending must be at least $1042$ for the premium card to be the better choice.
