Derrick joined a club that costs $7 per day. Is the cost over time a proportional or non-proportional relationship?

it is proportional

Step-by-step explanation:

ab: 2 n83b8eb7ebi. 8e yen in

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
