Help

1-16 are similar, Bree..we are just solving for different things in some of them.....here's a couple

1.   Interest = Principal * Rate *Time

      Interest =   1500 * .05 * 3  =  $225

5.    20  =   250 * r * 2

      20  =  500 * r       divide both sides by 500

      20/500 = r = .04   = 4%

10.   1440  = P *  .03 * 5

        1440 = P * .15      divide both sides by .15

        $ 9600  = P
