Beth has hamsters at her house. the number of hamsters is equal to the sum of the number of birds at kristins house and the number dogs at wendis house. john has the same number of cats as wendi has of dogs. if these four children have a total of 12 pets, how many pets are at each house?
i don't know how to solve this problem.

it's both, now can you answer my most recent question?

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
