Let n be the number of nickels and q be the number of quarters in the jar.
Worth of each nickle is $0.05 and worth of each quarter is $0.25. So worth of n nickles will be 0.05n and worth of q quarters will be 0.25q.
There are 150 total coins in the jar. So we can write the equation as:
n + q = 150 (Equation 1)
Total value of coins is $26.70. So we can write the equation as:
0.05n + 0.25q = 26.70 (Equation 2)
From Equation 1 value of n comes out to be n = 150 - q. Using this value in Equation 2, we get:
Using the value of q in Equation 1, we get the value of n to be 54.
This means, John has 54 nickles and 96 quarters in the jar.
Yes, you are correct. 365 times 5 is 1,825. 1,825 times 45 is 82,125.

Avery can explain to her school principal that 85% of juniors think there is a lot of homework because several indicators have increased.
<h3>What is an indicator?</h3>
An indicator is a datum that is taken as a reference to analyze the evolution or change of a fact over time. In this case, the indicators would be:
- Weekly hours used to do homework
- Number of students with work for after school.
According to the information, it can be inferred that 85% of Junior students consider that there is an increase in homework because there were the following changes compared to last year:
- Increase in hours spent on after school homework, last year the average was 5 hours, this year it is 8 hours.
- Increase in the number of students with after school jobs, last year it was 135 students, this year it is 215 students.
From the foregoing, it can be inferred that the number of homework has increased in Junior students and that is why now 85% of them consider that homework has increased.
