(i) Express the number of present students of everyday in percent.
(ii) Find the percentage of absent students of each day.​

yo answer should be 6 if im not mistaken

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

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
