Given the two options above, in order to come up with the best plan we have to calculate the future value of money in each plan.
compound interest is given by: $FV=p(1+ \frac{r}{100})^n$

Option 1
p=$500
r=2%=0.02
t=1 year
$FV=500(1+0.02)^1=$510$

Option 2
p=$500
r=2/12=1/6
n=1*12=12
hence:
$FV=500(1+\frac{ \frac{1}{6}}{100})^{12}
$
=$509.09
Comparing the two plans above, option 1 is the best.

b] Option 1 is the best because she will secure $510 as compared to option 2 which has interest rate that reduces her amount by $1 after one year due to annual charges. The total amount of money she will have at the end of the plan is $510.

The football fields at three different schools were measured, and it was found that their perimeters were 320 m, 360 m, and 400

Tomtit [17]

Let us say that,

<span>A = perimeter of football field of the 1st school</span>

B = perimeter of football field of the 2nd school

C = perimeter of football field of the 3rd school

So that:

A = 320 m

B = 360 m

C = 400 m

So the first thing we have to do to find for the minimum laps to make is to divide every perimeter by the smallest one, therefore divide all by 320 m, hence:

A’ = 1

B’ = 1.125

C’ = 1.25

Now multiply everything by a number such that all laps will be a whole number, in this case multiply everything by 8:

A’ = 8

B’ = 9

C’ = 10

Hence the laps to run are:

4 is the x value and -3/4 is the y value. (x,y)

To plot this point, move over to the right to 4, then go down 3/4. So the point will be in the bottom right quadrant.

A new car is purchased for 15500 dollars. The value of the car depreciates at 7.5% per year. What will the value of the car be,

mixer [17]

Answer:

$\$9,709.17$

Step-by-step explanation:

we know that

The formula to calculate the depreciated value is equal to

$V=P(1-r)^{x}$

where

V is the depreciated value

P is the original value

r is the rate of depreciation in decimal

x is Number of Time Periods

in this problem we have

$P=\$15,500\\r=7.5\%=0.075\\x=6\ years$

substitute

$V=\$15,500(1-0.075)^{6}=\$9,709.17$
