Carl opened a bank account that does not earn interest with $900. He deposits $30 per week. After how many weeks will Carl have $1260 in his bank account? A 12
B 30
C 42
D 360

B i worked it out in my head, sorry if i dont get it right

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
