Mariah wants to buy as many collectible dolls as possible, for $4.50 each. If she has $75.00 to spend, how many dolls can she buy? Which equation represents this situation?(1 point) Responses 75d=4.5 75 d is equal to 4 point 5 d+4.5=75 d plus 4 point 5 is equal to 75 4.5d=75 4 point 5 d is equal to 75 d4.5=75
The correct equation that represents this situation is:
4.5d = 75
If Jaylan takes the number of stamps he has and multiplies it by 5 and then subtracts 10, he gets 275. How many stamps does he have?(
To find the number of stamps Jaylan has, we can set up the equation:
5d - 10 = 275
Where d represents the number of stamps Jaylan has.
Now, let's solve for d:
5d - 10 = 275
Add 10 to both sides:
5d = 285
Divide both sides by 5:
d = 57
Therefore, Jaylan has 57 stamps.
To find out how many dolls Mariah can buy, we can use the equation:
4.5d = 75
where:
- d represents the number of dolls Mariah can buy
- 4.5 is the cost of each doll
- 75 is the total amount Mariah has to spend
So, the correct equation for this situation is:
4.5d = 75
To find the number of collectible dolls that Mariah can buy, we can divide the total amount of money she has ($75.00) by the cost of each doll ($4.50). Therefore, the equation that represents this situation is:
75 รท 4.5 = d
where d represents the number of dolls Mariah can buy.
