In mrs. garrett’s english class, 80% of the students were present last thursday. she had 20 students in class thursday. what is the total number of students enrolled in her class?

amount enrolled = 25

Step-by-step explanation:

amount enrolled * percent = student who were there

amount enrolled * .80 = 20

divide each side by .8

amount enrolled * .8/.8 = 20/.8

amount enrolled = 25

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: 12   they all have at least 28 days

step-by-step explanation: haha
