a woman put $580 into a saving account for one year . the rate of interest on the account was 6 half
%. how much was the interest for the year in dollars and cents?

Respuesta :

I don't know about American currency but, I think it is $617 and 70 cents like $617.70. 

6.5% = 6.5/100 = 0.065 
0.065 x 580 = 37.7 
$580 + $37.70 = $617.70
