A digital camera costs $185 and the sales tax rate is 5.7%. What is the total cost of the camera after tax. Round to the nearest
Eddi Din [679]
To find the total cost of the camera after tax, you need to find how much it will cost after the price is increased.

To do this, you need to multiple the original price by 1.057.

The 1 means it keeps it's original price (it is an increase not a decrease) and the 0.057 is the 5.7% increase added on (to find a percentage of a number you need to divide the percentage by 100 (5.7 ÷ 100 = 0.057)) and multiply it by the original value. 

185 * 1.057 = 195.545 or $194.55

Answer = A. $195.54
