In the sequence 1, 2, 4, an an , every nth term for n > 1 is created by the equation an=a(n? 1)? 2 an=a(n? 1)? 2 . by what percent is the 11th term greater than the 9th term in this sequence?

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
