Answer:
Number of students(n1)= 4,402
Step-by-step explanation:
Giving the following information:
Number of students= 4,512
Declining rate= 2.5%
<u>To calculate the number of students next year, we need to use the following formula:</u>
Number of students (n+x)= number of students (n0) / [(1+declining rate)^(n+x)
x= number of years
Number of students(n1)= 4,512/1.025
Number of students(n1)= 4,402

Answer:
Pam: $181
Amanda: $362
Julie: $452
Step-by-step explanation:
(What does Mike have to do with this problem?)
Let a = Amanda's pay
Let p = Pam's pay
Let j = Julie's pay
"Amanda made twice what Pam earned"
a = 2p
"Julie made $90 more than Amanda"
j = a + 90
j = 2p + 90
Pam earned p
Total salary
a + p + j = 2p + p + 2p + 90
Total salary
$995
2p + p + 2p + 90 = 995
5p = 905
p = 181
a = 2p = 2(181) = 362
j = 2p + 90 = 362 + 90 = 452
Answer:
Pam: $181
Amanda: $362
Julie: $452
