<span>You have to sum up three concepts, the cost before sales tax, the sales tax and the tip. The price before sales tax $11.75; the sales tax is the price times 8%, which $11.75 *8% = $11.75*8/100 = $11.75*0.08 = 0.94; and the itp is $2. Then, the equation is w = 11.75 + (0.08)(11.75) + 2, and the result is 14.69. So, the true statements are B and D.</span>
