a. Cost = $0.50
b. Cost = $1.05
c. Cost = $1.10
d. Cost = $0.45

Answer 1

According to the problem, Dunkin Donuts wants to markup the cost by 110%, which is equivalent to multiplying the cost by 1.1. Therefore, the cost of the donut is approximately $0.2381, which is not provided in the given options.

Step-by-step explanation:

Let's denote the cost of the donut as C. According to the problem, Dunkin Donuts wants to markup the cost by 110%, which is equivalent to multiplying the cost by 1.1.

So, the equation representing the cost of the donut is:

C × (1 + Markup Percentage) = Selling Price

Substitute the values:

C × (1 + 1.10) = Selling Price

C × 2.10 = Selling Price

Now, let's solve for C:

C =
`\frac{\text{Selling Price}}{2.10}`

C =
`(\$0.50)/(2.10)`

C ≈ $0.2381

Therefore, the cost of the donut is approximately $0.2381, which is not provided in the given options. There might be a mistake in the problem or the answer choices.
