22 1/5 miles per gallon

Step-by-step explanation:

Not sure if the answer is correct i think it is 45/2 turn this in to a proper fraction

becuase 1/90 gallons=1/4 miles so

1/4 times 90 again not sure if i correct.

answer: was that a question or answer?

step-by-step explanation:

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
