Answer:

Let's say something costs 100 pounds. If the cost is increased by 10 percent then it goes to 110 pounds. 10 percent of 110 is 11 so 110-11 is 99 (less than earlier. There you go.

PLEASE HELP. Solve for x
sergejj [24]

Answer:

x=8

Step-by-step explanation:

set up a proportion:

\frac{20}{4}=\frac{4x-7}{5}

simplify:

5 =\frac{4x-7}{5}

now solve this equation for x:

5 = \frac{4x-7}{5} \\25 = 4x - 7\\32 = 4x\\x = 8

Aaron invested $740 in an account paying an interest rate of 5%
vlada-n [284]

The amount of money   Justin would have in his account than Aaron, to the nearest dollar is $0

What is the future value formula for continuous compounding cash flow?

The future value, which is used to determine the worth of this investment of $740 made now in 18 years is as shown below:

FV=PV*e^(rt)

FV=the worth of the investment in 18 years=unknown

PV=the amount invested today=$740

e=mathematical exponential value=2.7182818

r=rate of interest which compounded continuously=5%

t=time of investment in years=18

FV=$740*2.7182818^(5%*18)

FV=$740*2.7182818^(0.90)

FV=$740*2.459603087981220

FV=$1,820.11

Justin:

FV=PV*(1+r/m)^(n*m)

PV=$740

r=5%

m=number of times in a year that interest is compounded=365

m=number of years=18

FV=$740*(1+5%/365)^(18*365)

FV=$1,819.99

difference=$1,820.11-$1,819.99

difference=$0.12($0 to the nearest dollar)
