Which of the following is true?
the rate of change of the function g(x) is -2.
20
the rate of change of f(x)is 14 times the rate of change of g(x).
the rate of change of f(x) is greater than the rate of change of g(x).
the product of the rate of changes of f(x) and g(x) is -6.

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
