Monique bought a shirt for $22.80 during a 30% off sale. How much does the shirt cost when it is not on sale?

29.64

Step-by-step explanation:

First we multiply 0.3 with 22.8.This will give us 6.84 which is the 30% off.Now we add 22.80 and 6.84 and we will get our answer 29.64.

$29.64

Step-by-step explanation:

30% = .30

$22.80 x .30 = 6.84

Next, 22.80 + 6.84 = 29.64

The shirt cost 29.64 when it is not on sale.

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
