Tell whether the number is prime or composite

Hello!

To tell whether a number is prime or composite, simply look at the factors of the given number.

If the number has exactly 2 factors, then it is prime.

If the number has 3 or more factors, then it is composite.

Hope it helps! :)

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
