For Mr.Rogers to pay his monthly bills he must make at least $1675 each month. he sells cars and makes a guaranteed salary of $850 per month plus $225 commission on each car he sells . what is the least number of cars he must sell each month to meet his monthly obligations ?请大家写步骤，谢谢！

Answer 1

你好
题意如下：Rogers先生为了付每月账单至少需要1675美元/月，他的工作是卖车，有一份固定收入（850美元/月）以及每卖掉一辆车都有225美元的提成。他每月至少卖多少辆车才能付清每月的账单？
解法如下：设还至少每月卖x辆车
则225x+850>=1675
225x>=825
x>=11/3
所以每月至少卖掉4辆车才行
希望对你有帮助
如有疑问，欢迎追问
望采纳~

Answer 2

解：设每月至少卖出X台。
由题意得，
225X+850≥1685
225X≥835
X≥3.7
又因为X为正整数，
所以X≥4
答：每个月最少卖出4台，才能够付每月的账单。

Answer 3

1675=850+225x

x=3.666666667
he must sell 4 cars each month to meet his monthly obligations
