Given, the charges to clip a dog's nail = $n
The charges to wash the dog = $w
The charges to cut a dog's hair = $h
The total charges Jasmin take for 1 dog = $n+$w+$h = $(n+w+h)
For 4 dogs we can get total charges by multiplying the total charge for 1 dog with 4.
So, the total charges for 4 dogs = $(n+w+h) × 4 = $ 4(n+w+h) = $(4n+4w+4h)
So we have got the required answer.
The total charges for 4 dogs = $ 4(n+w+h) = $(4n+4w+4h)
Your question is incomplete .....
If you have built 25 cars, and they are 36 dollars per, then multiply 25 and 36 for the amount of money. This will result with 25*36=900. Since we already have 900 dollars worth, we subtract that from the goal of 1620, leaving us with 1620-900=720. Now, divide this by the price per car for the amount of cars needed to get to this goal. 720/36=20 cars
Hope this helps!
