A beverage is made by mixing 1 part of water with 3 parts of fruit juice. How many parts of water are mixed with one part of fruit juice? A. 1/3
B.1/2
C.3/2
D.3/1

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
