1/30
because 30+40+50=120
40/120= 1/30
Answer:
$48
Step-by-step explanation:
The dress's price is $40. That is 100% of the dress's price.
Since tax is 20%, you need to add 20% to the 100%.
100% + 20% = 120%
The total cost including tax will be 120% of the cost of the dress.
To find a percent of a number, multiply the percent by the number.
120% of $40 =
= 120% * $40
= 1.2 * $40
= $48
