The number of people is inversely proportional to the number of days for a bag of rice to last. If it takes 8 people for a bag of rice to last 5 days, how many days would it take 10 people?​

4

Step-by-step explanation:

the ratio is 8/5, so the inverse would be 5/8, then it went up to 10, so it would be 10/4

89

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
