Ana is playing a quiz game and needs more than 500 points to advance to the next level. She earns 18 points for each correct answer loses 6 points foWhat is an inequality that represents all the possible combinations of c, the number of correct answers, and w, the number of incorrect answers that Ana can get and move to the next level?

According to the question, the numver of points she needs to advance to next level should be more than 500.

Let the number of points be m

Let's find the number of points (m)

where, 18 is the points gained through each correct answer and c is number of correct answers.

where, 6 is points lost for each wrong answer and w is the number of wrong Answers.

Total points (m)

gained points by Correct answer - points lost by wrong answer

The total points (m) is great than 500

So, the Appropriate inequality is : -

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
