How much money has to be invested at 5.9% interest compounded
continuously to have $15,000 after 12 years?
A. $7427.73
B. $7402.26
C. $7465.50
D. $7389.43

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

i agree because i see the other persons thinking is clear

i think the answer is 90 hope this
