The martins drove the 468 miles between memphis, tennessee and cincinnati, ohio in one day. if they left memphis at 7 a. m. and arrived in cincinnati at 4 p. m., what was the martins’ average speed?

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
