Joan Deere sells tractor parts. she gets a base salary of $1255 per month plus a commission of 8.5% of any sales greater than $10000. She sold $15000 in parts last month. (She only gets commission on the money greater than $10000), How much was her monthly check for?

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
