Answer 1

Let's calculate the final price at each store based on the provided discounts:

Store A:

• First discount: 10% off of $360 \[ 10% \text{ of } 360 = 0.10 \times 360 = 36 \] So, the new price after the first discount: \[ 360 - 36 = 324 \]
• Second discount: 10% off of $324 \[ 10% \text{ of } 324 = 0.10 \times 324 = 32.4 \] So, the final price after the second discount: \[ 324 - 32.4 = 291.6 \]

Store B:

• Discount of 15% off of $360 \[ 15% \text{ of } 360 = 0.15 \times 360 = 54 \] So, the final price: \[ 360 - 54 = 306 \]

Store C:

• First discount: $35 off of $360 \[ 360 - 35 = 325 \]
• Second discount: 10% off of $325 \[ 10% \text{ of } 325 = 0.10 \times 325 = 32.5 \] So, the final price after the second discount: \[ 325 - 32.5 = 292.5 \]

Now let's summarize the final prices:

• Store A: $291.6
• Store B: $306
• Store C: $292.5

Now we can compare:

• Store A: $291.6
• Store B: $306
• Store C: $292.5

The store with the least amount paid is Store A.

The correct answer is: b. You can get the lowest price at Store A.
