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
