You pick up a 1.5 litre bottle of water.
One friend picks up a 200 cl bottle.
Another friend picks up a 330 ml bottle.

im not quite sure if this is right but i got 5.6 oisutuve

step-by-step explanation:

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
