Quizplus · Accepted Answer

The total amount in the cash register is the sum of the sales and the sales tax. If we let x be the amount of sales, then the sales tax is 5% of x, or 0.05x. The equation representing the total amount is x + 0.05x = 1470. Combining like terms gives 1.05x = 1470. Solving for x gives x = 1470 / 1.05 = 1400. The sales tax collected is 1470 - 1400 = $70.
