A hiker starts hiking in Death Valley at an elevation of 143 feet below sea level. He climbs up 435 feet and enjoys the view. Then he climbs up another 267 feet. What is his new elevation relative to sea level?

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

answer: about 22.67
