As, Don has 4 more than 5 times the number of marbles mark has, so the number of marbles Don has

Question says that the total number of marbles is 70. So, the equation will be...

So, the number of marbles Mark has = 11

and the number of marbles Don has =

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
