To Calculate: How much money was invested in each fund if a teacher invested $5000 in three funds. After a year they had $5450. The growth fund had a return rate of 12%, the income fund had a return rate of 8% and the money market fund had a return rate of 5%. The teacher invested twice as much in the income fund as in the money market fund.
He invested $2000 in growth fund, $2000 in income fund and $1000 in market fund.
Given information:
A teacher invested $5000 in three funds. After a year they had $5450. The growth fund had a return rate of 12%, the income fund had a return rate of 8% and the money market fund had a return rate of 5%. The teacher invested twice as much in the income fund as in the money market fund.
Calculation:
Consider the given information.
Let x represents the amount invested in growth fund, y represents the amount invested in income fund and z represented the amount invested in money market fund.
He invested $5000 in three funds.
He invested twice as much in the income fund as in the money market fund.
After a year he had $5450. The growth fund had a return rate of 12%, the income fund had a return rate of 8% and the money market fund had a return rate of 5%.
So the income earned is:
Multiply equation 1 by 12 and subtract to equation 3.
By equation 2 and 4:
Put value of z in equation 2.
Put value of y and z in equation 1.
He invested $2000 in growth fund, $2000 in income fund and $1000 in market fund.
