What is the total price for the four items including sales tax? 4 items:
Stereo-$395.95
Printer-$159.95
Phone:$750.00
BT Speaker-$129.95 ( Student discount-25%, Sales Tax- 8.25%)

$1165.73

Step-by-step explanation:

We have 395.95+159.95+750+129.95=1435.85. Once we have this, we add the student discount of -25%. This rounds to 358.96. We subtract this from the total and get 1076.89. After the student discount, we add the sales tax of 8.25%. This adds a total of 88.84 to the final amount. After adding this we get a final total of $1165.73
