mrs. brown's girl scout troop had a car wash to earn some funds. They saved 1/6 of the money. They used 1/2 of the remaining money to go horseback riding. They then had $100.00 left. How much did they initially make washing cars?

1/2(5/6)x = 100

5/12x = 100

Solve for x.

How do you get 5/6

240

To find out how much money Mrs. Brown's Girl Scout troop initially made from the car wash, we can work backwards from the given information.

Let's denote the initial amount of money they made from the car wash as "x".

Step 1: Mrs. Brown's troop saved 1/6 of the money. This means they had 5/6 of the money remaining.

5/6 * x = Remaining money after saving

Step 2: They used 1/2 of the remaining money for horseback riding, which left them with $100.00.

(5/6 * x) * (1/2) = $100.00

To isolate x, we can multiply both sides of the equation by 2/5.

(5/6 * x) * (1/2) * (2/5) = $100.00 * (2/5)

Simplifying the equation:

(5/6 * x) * (1/5) = $100.00 * (2/5)

Now, canceling out the common factors:

(1/6 * x) = $40.00

Multiplying both sides of the equation by 6:

x = $240.00

Therefore, Mrs. Brown's Girl Scout troop initially made $240.00 from the car wash.
