5) The cost of renting a car is $200/day plus $0.50/mile. If a 250 mile trip would take 2 days, how much would it cost?

It would cost $525

I'm not certain this is correct

I added 200 + 200, then i multiplied 0.50 x 250

the total would be $525

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
