1. Create the following variables: a. item, tagPrice, quantity, shippingMethod, tax, stateTax, totalPrice b. Initialize totalPrice with the value 0 and stateTax to 1. 2.

VGC is $399 - this stands for Video Game Console c. Any other item or input should alert We do not carry that item, try again! and reload the page using the location.reload(); instruction. 3.
