Final answer:
Dara paid $11.25 for the doll after applying a 75% discount to the original price of $45. The discount amount was $33.75.
Step-by-step explanation:
The question is asking us to calculate the final price Dara paid for a doll that was originally priced at $45 but was on sale with a 75% discount. To find the discounted price, we need to calculate 75% of $45 and then subtract it from the original price. The calculation is as follows:
75% of $45 = 0.75 × $45 = $33.75
The amount that will be subtracted from the original price is $33.75. Therefore, Dara paid:
$45 - $33.75 = $11.25
So, the correct answer is a) $11.25.
