Answer:
a.$7,096
Step-by-step explanation:
- total amount A = s(\frac{(1+\frac{r}{n}) ^{n*t}-1 }{\frac{r}{n} } )[/tex]
[this is the formula used when certain amount is added at regular intervals and if the interest is COMPOUNDED]
(here,
s=deposit added at the end of each quarter= $500
n= number of times interest is compounded per unit 't'=4
t=total time = 3 years
r=interest rate ( expressed in decimal or fraction not in %) = 12/100 = 0.12 )
- A= 500(\frac{(1+\frac{0.12}{4}) ^{4*3}-1 }{\frac{0.12}{4} } )[/tex]
- by solving further,
A

Let x person in 1 van and y persons in 1 bus
so for school A took 2x+2y=106
for school B took 8x+y=151
make a system
solve it:
multiply second equation by 2
<span> 2*8x+2*y=2*151</span>
16x+2y=302
second equation minus first we have:
16x+2y-2x-2y=302-106
14x=196
x=14 - persons in 1 van
to find y put x=14 in equation:
2x+2y=106
2*14+2y=106
2y=106-28
2y=78
y=39
Answer: 1 van can carry 14persons, 1 bus can carry 39 persons
