pls mark brainliest!

30

Step-by-step explanation:

age of luigi=L   age of mario=M

M=L+3

Substitute 27 for L, since luigi is 27

M=27+3

M=30

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
