Monte receives an allowance of 20 dollars each month how much money will he receive by the end of the year

Monte will receive 240 dollars by the end of the year. 

If Monte receives an allowance of 20 dollars each month, and we need to find out how much he gets in a year, we need to find the number of times that he will get this allowance. Since there are 12 months in a year, and since Monte receives this allowance every month, that means that Monte will receive 20 dollars 12 times during the course of a year. To find how much money that is, we multiply the two quantities. 12 * 20 is 240, so Monte receives $240 each year.
