Calculate Total Price: Identify the correct way to calculate the total price including sales tax. To find the total price including tax, you multiply the price by 1 plus the tax rate. Calculation: Total price = p * (1 + tax rate) Tax rate given is 6.5%, or 0.065 in decimal form.Check First Expression: Check the first expression to see if it represents the total price plus tax. First expression: 1 + 0.065 p This expression adds 1 dollar to 6.5% of the price, which does not correctly calculate the total price including tax.Check Second Expression: Check the second expression to see if it represents the total price plus tax. Second expression: (1 + 0.065)p This expression multiplies the price by 1 plus the tax rate, which is the correct way to calculate the total price including tax.Check Third Expression: Check the third expression to see if it represents the total price plus tax. Third expression: 1.065 p This expression multiplies the price by 1.065, which is equivalent to multiplying the price by 1 plus the tax rate, and thus correctly calculates the total price including tax.Check Fourth Expression: Check the fourth expression to see if it represents the total price plus tax. Fourth expression: p + 0.065 p This expression adds 6.5% of the price to the original price, which is the correct way to calculate the total price including tax.Identify Incorrect Expression: Identify the expression that does NOT represent the total price plus tax. The first expression, 1 + 0.065 p, does not correctly calculate the total price including tax because it adds 1 dollar to 6.5% of the price instead of multiplying the entire price by 1 plus the tax rate.

Lauren went shopping for a new phone. Sales tax where she lives is $6.5 \%$ . If the price of the phone is $p$ dollars and cents, which expression does NOT represent the total price plus tax? $\newline$ $1+0.065 p$ $\newline$ $(1+0.065) p$ $\newline$ $1.065 p$ $\newline$ $p+0.065 p$
