Let's solve this step-by-step:

1. Let's first set up the equation to represent this situation. Since Mariah wants to buy as many dolls as possible, we can use the equation "4.5d = 75," where d represents the number of dolls she can buy.

2. Now, let's solve the equation. Division is the inverse operation of multiplication, so we'll divide both sides of the equation by 4.5 to isolate d:

4.5d / 4.5 = 75 / 4.5

This simplifies to:

d = 16.67 (rounded to two decimal places)

3. Since you cannot buy a fraction of a doll, we need to find the whole number of dolls she can buy. As d represents the number of dolls she can buy, we round down the decimal answer to the nearest whole number:

d ≈ 16

Therefore, Mariah can buy 16 collectible dolls.

Answer 3

To solve this problem, we need to divide the total amount of money Mariah has by the cost of each collectible doll.

First, let's set up the equation to represent this situation. Let's use the variable "d" to represent the number of dolls Mariah can buy.

The equation that represents this situation is:

4.5d = 75

Now, let's solve for "d". Divide both sides of the equation by 4.5:

d = 75/4.5

Calculating this, we find that Mariah can buy approximately 16.67 dolls. However, since we are dealing with whole dolls, we need to round down to the nearest whole number. Therefore, Mariah can buy 16 collectible dolls.
