Answer:

4 1/2 years

Step-by-step explanation:

T = 100 I /PR

Where

T = time

I = interest

P = principal

R = rate

Given

P = $3500

R = 6%

I = $945

T = ??

Therefore

T = 100 x 945 /3500 x 6

= 94500/21000

Cancel out zeros

= 945/210

Divide the numerator and denominator by 5

= 189/42

Divide both by 7

= 27/6

Divide by 3

= 9/2

= 4 1/2 years
