First, we need to solve the price with the discount.
We need to change the 15 percent into a decimal, by simply just dividing 15 by 100 equaling out to 0.15.
Now multiply the original price by 0.15. 18×0.15 equals to 2.7 but since we're talking about money we must add another zero, making it 2.70.
Now since we figured out $2.70 is the discount, we must subtract it from the price.
18-2.70= $15.30.
But now we have to figure out how much the sales tax. Divide 6 by 100 to get the decimal. 0.06.
Multiply 0.06 by 15.30 to get $9.18.
Since 9.18 is the sales tax, we must add it to the price.
15.30+9.18 equals $24.48.
Therefore, the total price paid is $24.48.
hope this helps!
