Sarah takes courses on a quarter system. three times a year, she takes 15 credits at a tuition rate of $ 280 per credit; her fees are $ 200 per quarter and her room in a shared house costs $ 140 per week. round your answer to the nearest dollar

5 x 14?

im new, sorry if this is wrong.

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

thats not a system of equations, that is a solution
