3. there is 4 inches of water in the swimming pool before the day started. the rainfall is falling at 3 inches per minute. a. write an inequality for how much water is in the pool, let x represent the minutes. b. graph the inequality (just give me the points.)

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
