Question

Terry invests $1500 in two mutual funds. The first year, one fund grows 3.8% and the other grows 6%. Write a polynomial to represent the amount Terry's $1500 grows to in that year if x represents the amount he invested in the fund with the lesser growth rate.

Answer 1

If x = the amount in the lesser fund
the amount in the greater fund would be (1500 - x)

0.06(1500 - x) + 0.038x

90 - 0.06x + 0.038x

90 - 0.022x

Now add the 1500

1500 + 90 - 0.022x

ANSWER

The binomial (1590 - 0.022x)
