Question 467015
Let x = the amount invested at 5% per annum. Then, ($25,000-x) would be the remainder invested at 4% per annum.
The the sum of the incomes earned on these two amounts can be expressed as (after changing the percentages to their decimal equivalents):
{{{0.05x+0.04(25000-x) - 1140}}} Simplify and solve for x.
{{{0.05x+1000-0.04x = 1140}}}
{{{0.01x = 140}}}
{{{x = 14000}}} and...
{{{25000-x = 11000}}}
$14,000 was invested @ 5% and $11,000 was invested @ 4%
