Come on, Kat ! The question tells you everything you could
possibly want to know, except what's for dinner tomorrow.
It gives you the formula at the bottom.
The formula is:
Interest = (Principle) x (Rate) x (Time) .
Above that, in the story, it gives you 3 of the 4 quantities in the formula:
Interest = $656
Principle = $1,000
Rate = 4.1% (that's 0.041)
Do you think you could write those numbers into the formula,
and find out what the (Time) is ?
656 = (1,000) x (0.041) x (T)
Divide each side by 41 .
You're welcome.
