Answer:
<h2>240 people</h2>
Step-by-step explanation:
Step one:
given data
Number of Students in a bus= 36
Number of Adults in a bus= 4
Total number of persons in a bus= 36+4= 40 persons
Step two:
in one bus there are 40 people
in 6 filled buses there are 6*40
=240 peoples.
Therefore there are 240 people going on the field trip
a) For principal amount P, interest rate r, and number of years t, the amortization formula for the monthly payment A is ...
... A = P(r/12)/(1 -(1 +r/12)^(-12t))
... A = 22500·(0.06/12)/(1 -(1 +0.06/12)^(-12·20)) ≈ 161.20
The monthly payment is $161.20.
b) After 240 payments, the amount repaid is
... $161.20·240 = $38,688
c) (22500/38688)·100% = 58.2% is paid toward principal
The remaining amount, 41.8% is paid toward interest.
No it is not valid because you only asked 50 students not every student so it could not be 40%.
First, turn 70% into a decimal by dividing 70 by 100.
70% ⇒ 0.70
Multiply 120 by 0.70.
120 × 0.70 = 84
Now we know that 84 students are involved in extracurricular activities. Subtract 84 from 120 to find the amount of students who are <em>not</em> involved in extracurricular activities.
120 - 84 = 36
