Trey and his mom stopped at a railroad crossing to let a train pass. as the train began to pass, trey counted 6 cars in the first 10 seconds. it took the train 2 minutes and 45 seconds to clear the crossing at a constant speed. which of the following was the most likely number of cars in the train?

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
