What is the total amount and the amount of interest earned on $6,500 at 6% for 25 years?
NNADVOKAT [17]

Answer:

Total amount earned after 25 years=$27,897.16

Step-by-step explanation:

Step 1: Express formula for calculating total amount

The total amount after 25 years can be expressed as;

A=P(1+r)^n

where;

A=total amount after 25 years

P=principal amount

r=annual interest rate

n=number of years

Step 2: Substitute values in the expression

In our case;

P=$6,500

r=6%=6/100=0.06

n=25 years

replacing in the original expression;

A=6,500(1+0.06)^25

A=27,897.16

Total amount earned after 25 years=$27,897.16

ozzi

Answer:

J= 40+13t

I= 80+9t

they are equal at 10 weeks

Step-by-step explanation:

So we can start this by writing our equations

J= 40+13t

I=80+9t

To figure out when they're equal set the two equations equal to each other and solve for t

40+13t=80+9t

subtract 40 and 9t from both sides to get

40=4t

divide by 4 and get

t=10
