We have a question: Bert has a garden shop. He buys his products in a warehouse and sells them for $10 more in his shop. From each sale, he has to pay 10% of the value in tax. One day a client came to his shop and bought a barrel for $90. How Much money did Bert make on this sale?
And an answer: 1
So how you got the answer?
First, we need to know how much Bert paid for the barrel in the warehouse, and that is 90 - 10 = $80. The tax from the sale stands at 10 / 100 * 90 = $9. That means Bert earned 90 - 9 - 80 = $1 on the sale.

We have a question: The number of elephants at Gestures For Good park is 3 times as many as the number of elephants at We Preserve For Future park. If there are 70 elephants at We Preserve For Future, calculate the total number of elephants in the two parks.
And an answer: 280
So how you got the answer?
At We Preserve For Future, the number of elephants is 70, 3 times the number at Gestures For Good park, meaning there are 3 * 70 = 210 elephants at Gestures For Good park. The total number of elephants in the two parks is 210 + 70 = 280.

We have a question: Andy is mixing blue, green and white paint in a 1 : 2 : 5 ratio. If he uses 6 gallons of green paint, how many gallons of paint does he use total?
And an answer: 24
So how you got the answer?
First find the number of gallons of blue paint by multiplying the gallons of green paint by the ratio between the blue and green paint: 1 blue gallon / 2 green gallons * 6 gallons = 3 gallons. Then find the number of gallons of white paint by multiplying the gallons of green paint by the ratio between the white and green paint: 5 white gallons / 2 green gallons * 6 gallons = 15 gallons. Then add the number of gallons of each color to find the total number of gallons of paint: 6 gallons + 3 gallons + 15 gallons = 24 gallons.
