What is the range for the function represented by these ordered pairs?

(9, 3) (12, 4) (15, 5)

a. 3, 4, 5
b. 3, 4, 5, 9, 12, 15
c. 9, 12, 15
d. 1, 2, 3, 4, 5, 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
