Answer:

$31.80

Explanation:

  • In order to determine the total cost of the watch, we want to multiply the tax percentage by the price without the tax to determine the tax amount in dollars.
  • Then we'll add this to the price without the tax to find the total cost:

(tax percentage * watch price) = tax amount

tax amount + watch price = total cost

Note that 6% is the same as 0.06:

0.06 * 30 = 1.8

1.8 + 30 = 31.80

Thus, the total cost is $31.80
