Answer 1

Answer: Part A: $440.99, Part B: $471.86, Part C: $534.86

Explanation:

Part A: To find the subtotal before tax, we need to apply the 30% coupon to the total price of the television and the wall mount. The total price is $600 + $29.99 = $629.99. The coupon reduces the price by 30%, which is equivalent to multiplying by 0.7. So, the subtotal is $629.99 x 0.7 = $440.99.

Part B: To find the final total after tax, we need to add the 7% state sales tax to the subtotal. The tax is calculated by multiplying the subtotal by 0.07. So, the tax is $440.99 x 0.07 = $30.87. The final total is the subtotal plus the tax, which is $440.99 + $30.87 = $471.86.

Part C: To find the new total with the tip, we need to add the 10% tip to the final total. The tip is based on the original purchase price before the discount, which is $629.99. The tip is calculated by multiplying the original price by 0.1. So, the tip is $629.99 x 0.1 = $63.00. The new total is the final total plus the tip, which is $471.86 + $63.00 = $534.86.
