Algebraically manipulating the formula for finding the simple interest, I = Prt, find the time period in years that $16,000 was deposited in a savings account which earned $4,000 in interest at a simple interest rate of 6%.
42 months
60 months
70 months
50 months
None of these choices are correct.

70,000 + 6,000 + 800 + 30

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

it is a secret for it not to be compromised sorry

step-by-step explanation:

i’m sorry but i don’t know sorry
