To find the rate of the discount, we need to calculate the difference between the original price and the sale price, and then express it as a fraction and a percentage.
a. To calculate the discount rate as a fraction, we can use the formula:
Discount rate = (Original price - Sale price) / Original price
In this case, the original price is $18.00 and the sale price is $15.00. Plugging these values into the formula, we have:
Discount rate = ($18.00 - $15.00) / $18.00
Simplifying this expression, we get:
Discount rate = $3.00 / $18.00
To simplify further, we can divide both the numerator and denominator by the greatest common divisor (GCD), which in this case is 3:
Discount rate = $1.00 / $6.00
Therefore, the rate of the discount, written as a fraction, is 1/6.
b. To express the discount rate as a percent, we can multiply the discount rate as a fraction by 100.
Discount rate as a percent = (Discount rate as a fraction) * 100
Using the discount rate we found above, we have:
Discount rate as a percent = 1/6 * 100
To calculate this, we divide 100 by 6:
Discount rate as a percent ≈ 16.67%
Rounded to the nearest hundredth of a percent, the rate of the discount is approximately 16.67%.
