How much simple interest would you earn for 5 years at 7 with a beginning principal of $8 000.00

asambeis [7]

I=PRT
r=rate in percent
t=time in years
p=principal

convert percent to decimal
assuming you means at 7%
percent means parst out of 100
7%=7/100=0.07

so ow we have
p=8000
r=0.07
t=5
i=8000 times 0.07 times 5
I=40000 0.07
I=2800

interest=$2800

madam [21]

Answer:

Step-by-step explanation:

a₁ = 10

a₂ = 6

d = a₂ - a₁ = 6 - 10 = -4

n = 16

a₁₆ = a₁ + (n-1)•d = 10 + (16-1)•(-4) = 10 - 60 = -50

$S_{n}=\dfrac{a_1+a_n}{2}\cdot n\\\\\\S_{16}=\dfrac{10-50}{2}\cdot 16=-40\cdot8=-320$
