Solve the system of equations using elimination.

8x + 7y = -16
10x + 7y = -6

A) (3, 6)
B) (8, 5)
C) (7, 10)
D) (5, -8)

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

answer:

your answer is: c. 196 7/8 in^3.
