Frank’s electric bill has a cycle day of the 3rd and a due date 8 days later with a one day grace period. what happens if frank pays his electric bill on the 12th of the month?

Frank’s electric bill has a cycle day of the 3rd

And the due date of the bill is 8 days later

that is 3+8 = 11th of that month is the due date

The bill is to be paid by 11th

But 1 day grace period is given

So

11+1

=12

If one pays the bill by 12th of that month , then no penalty will be imposed.

And

Frank pays his electric bill on the 12th of the month

So no penalty will be imposed.

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
