How long will it take for $8,000 to earn $200 in interest at 12.5% simple interest?

it will take 4.8 months.

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount investment.

P represents the principal or amount invested

R represents interest rate

T represents the duration of the investment in years.

From the information given,

P = 8000

R = 12.5

I = 200

200 = (8000 × 12.5 × T)/100 = 1000T

T = 200/1000

T = 0.2

Converting to months, it becomes

0.2 × 12 = 4.8 months

0.2years

Step-by-step explanation:

Simple interest(si)=$200

Principal(p)=$8000

Rate(r)=12.5%

Time(t)=?

t=(100xsi)/(pxr)

t=(100x200)/(8000x12.5)

t=20000/100000

t=0.2 years

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
