Rosie washes clothes for two families the first family pays her $500 more per month than the second. her total earning per month is $3200. how much does she earn from each families?

Step-by-step explanation:

We know that the total monthly payment is 3200, so if we call Pa (family A`s payment) and Pb (Family B's payment) the payments:

So if we replace Pa in the first ecuation:

then Pa+Pb=3200 => Pa= 3200-1350= $1.850

Good Luck!

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
