You haven't provided a list but the following should help you:.

We need a fraction which has a value between 1/2 and  4/5.

If we convert the fractions to tenths ( because 10 is the LCD of 5 and 2) then this will be easy.

5/10 < __ < 8/10.

So we could choose 7/10.

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
