Answer this question:Jay has decided to save money from his paycheck every week. He has decided that he will increase the amount he saves each week by 10 dollars. If he started by saving 20 dollars this week, how much will he have saved in a month from now?
In one week he will have saved 20 + 10 = 30 dollars. In two weeks he will have saved 30 + 10 = 40 dollars. In three weeks he will have saved 40 + 10 = 50 dollars. At the end of week four, he will have saved 50 + 10 = 60 dollars.
The answer is 60.

Answer this question:The Franzia wine is three times as old as the Carlo Rosi, while the Carlo Rosi is four times older than the Twin Valley. Calculate the total age of the three brands of wine if the Carlo Rosi is 40 years old.
If the Franzia wine brand is three times as old as the Carlo Rosi, then the Carlo Rosi is 3 * 40 = 120 years old. The total number of years the Carlo Rosi and the Franzia wine brands have been around is 120 + 40 = 160 years. The Carlo Rosi is four times older than the Twin Valley wine brand, meaning the Twin valley wine brand is 40 / 4 = 10 years old. Together, the three bands have a total of 10 + 160 = 170 years of existence.
The answer is 170.

Answer this question:Mark wants to set the record for most consecutive ropes jumped. The record is 54,000. He can jump 3 times a second. How many hours would he need to jump rope?
He can jump 3 * 60 = 180 times per minute. So he can jump 180 * 60 = 10,800 per hour. So it would take him 54,000 / 10,800 = 5 hours.
The answer is 5.

Answer this question:Jocelyn bought a car 3 years ago at $4000. If the car's value has reduced by 30%, calculate the current value of the car.
If Jocelyn bought the car 3 years ago at $4000, the car's value has reduced by 30 / 100 * $4000 = $1200. The current value of the car is $4000 - $1200 = $2800.
The answer is 2800.
