Jan charges $50 per hour and he has to pay $15 per day for gas he made $1315 in four days how many hours did he work

15*4=60 for the gas for 4 days. 1315+60=1375 to find gross not net profit. 1375/50=27.5

He worked 27.5 hours (extra: he worked 6.875 hours per day)

21/58.

hope to be marked brainliest

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
