Final answer:
The percent discount for posting four jobs is calculated by dividing the discount amount ($45.00) by the original price ($495.00), then multiplying by 100%. This results in a 9.0909...% discount, which is rounded to 9.1% (option a).
Step-by-step explanation:
The student has asked to calculate the percent discount given when purchasing four job postings on an online job search site. The original price for one job posting is $495.00, while the price per job when purchasing four postings is $450.00.
To find the percent discount, we first need to determine the amount of the discount by subtracting the reduced price from the original price:
Discount = Original Price - Reduced Price
Discount = $495.00 - $450.00
Discount = $45.00
Next, we calculate the percent discount by dividing the discount amount by the original price and then multiplying by 100 to get the percentage:
Percent Discount = (Discount ÷ Original Price) × 100%
Percent Discount = ($45.00 ÷ $495.00) × 100%
Percent Discount = 0.090909... × 100%
Percent Discount = 9.0909...
Rounded to the nearest tenth of a percent, the percent discount is 9.1%, which corresponds to option (a).
