A repair company charges a flat fee of $40 plus $30 for each hour (h) spent making a repair. Which of the following equations could be used to find the charge(c) for any service call? (1)c=$30h
(2)c=$40h
(3)c=$40+$30h
(4)c=$40h+$30h
(5)c=$30+$40h

(3) c=$40+$30h

Step-by-step explanation:

Since there is an initial fee for a repair, that is just added. Since the hourly fee depends on how long it takes, it needs a variable with it.

10 glasses of juice could be made with 5 carrots, 1,500 orange juice, 2,000 papaya juice.

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
