Let's solve the problem step by step.

Given Information:

• The wholesale price of the electric stove = $689.

(a) Department store:

• The markup on the wholesale price = 60%.
• Eric gets a 20% discount on the in-store price.

First, calculate the in-store price before the discount: $\text{In-store price} = 689 + (689 \times 0.60) = 689 \times 1.60 = 1102.40$

Now, calculate the price after the 20% discount: $\text{Price after discount} = 1102.40 - (1102.40 \times 0.20) = 1102.40 \times 0.80 = 881.92$

So, Eric pays $881.92 at the department store.

(b) Superstore:

• The markup on the wholesale price = 40%.
• Eric does not get any discount.

Calculate the in-store price (no discount): $\text{In-store price} = 689 + (689 \times 0.40) = 689 \times 1.40 = 964.60$

So, Eric pays $964.60 at the superstore.

(c) True Statement:

• At the department store, Eric pays $881.92.
• At the superstore, Eric pays $964.60.

Therefore, the correct answer is: $\text{Eric would pay less for the electric stove at the department store.}$

Final Answers:

• (a) $881.92
• (b) $964.60
• (c) Eric would pay less for the electric stove at the department store.

Here are 5 related questions for deeper practice:

1. What would the price be at the department store without the loyalty program discount?
2. If Eric had a 10% discount at the superstore, what would the final price be?
3. What percentage difference is there between the prices at the two stores?
4. How much would Eric save by purchasing the stove at the department store instead of the superstore?
5. If the wholesale price increased to $700, how would that impact the prices at both stores?

Tip: When dealing with multiple percentages, apply the markup or discount step by step to avoid confusion.
