Eric downloads a 10% off any one item coupon and goes shopping at Gadgets Galore, where he buys a digital camera for $93 and an extra battery for $11.99.

Part 1)))Eric has to pay 8% sales tax after the coupon is applied. How much is his total bill if necessary round to the nearest cent.

To calculate Eric's total bill after the 10% off coupon is applied, we need to find 10% of the total price of the digital camera and extra battery.

10% of $93 (price of the digital camera) = $9.30
10% of $11.99 (price of the extra battery) = $1.199

Now, subtract these amounts from the original prices:

Digital camera price - $9.30 = $93 - $9.30 = $83.70
Extra battery price - $1.199 = $11.99 - $1.199 = $10.791 (rounded to the nearest cent = $10.79)

To calculate the total price before sales tax, add the prices of the digital camera and extra battery:

Total price before tax = $83.70 + $10.79 = $94.49

Now, calculate the 8% sales tax on the total price before tax:

Sales tax = 8% of $94.49 = $7.56

Finally, calculate the total bill by adding the total price before tax and sales tax:

Total bill = $94.49 + $7.56 = $102.05

Therefore, Eric's total bill after the 10% off coupon and 8% sales tax is $102.05.
