The decker car rental company charges $25.40 plus 20¢ per mile to rent a car. the equation 25.4+0.2m=c represents the cost to rent a car from decker. bob's car rental charges $15 plus 60¢ per mile. the cost to rent a car from bob's is represented by the equation 15+0.6m=c . at what mileage (m) would the cost of renting a car be the same for both companies?

1 is c

2 is a

3 is a

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
