Solve. {d+e=2 {d−e=4 use the substitution method. there are an infinite number of solutions. there is no solution. the solution is (5, 1). the solution is (3, −1).

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

too hard the other guy did it
