Answer

$1620.00

Explanation

This question is asking how much money she can make while working and maintaining a 90 average. The average is calculated by dividing the total points by the total hours worked. First, we need to find out how many points she needs to maintain a 90 average. If she works for 2 hours, she loses 1 point. So, for every 2 hours of work, she has 1 point less. Let's denote the total points she needs to maintain a 90 average as P. We can set up the equation as follows:P = 90 \times 2 = 180This means she needs 180 points to maintain a 90 average. Next, we need to find out how many hours she needs to work to get these 180 points. Since she loses 1 point every 2 hours, she needs to work for 180 hours to get 180 points. Finally, we need to calculate how much money she can make in 180 hours. Since she earns \[\]9.00 per hour, she can make: \[180 \times \$9.00 = \$1620.00\] So, she can make 1620.00 while still maintaining a 90 average.
