Quizplus · Accepted Answer

The total amount in the cash register is the sum of the sales and the sales tax. Let $x$ be the amount of sales before tax. The tax is 5% of $x$, or $0.05x$. The equation representing the total amount is $x + 0.05x = 1155$. Simplifying, $1.05x = 1155$. Solving for $x$, we get $x = 1100$. The tax is 5% of 1100, which is $0.05 \times 1100 = 55$. Therefore, the amount that is the tax is $\$55$.
