Question 664889
let x be the amount you invest at 6%. Then {{{6300 - x}}} is the amount invested at 7%
You are told the interest from both investments is the same. So
{{{x * 0.06 = (6300-x) * 0.07}}}
{{{0.06x = 441 - 0.07x}}}
{{{0.13x = 441}}}
{{{x = 3392.31}}}
invest 3392.31 at 6% and 6300-3392.31 at 7%
