Terry invests $1500 in two mutual funds. The first year, one fund grows 3.8 percent and the other grows 6 percent. 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.
It's probably too late to help you with this particular problem, but I can give you tips on how to parse word problems in general!
It's always a good idea to break down the information as much as possible and assign any needed variables. For example, we're told that:
1) $1500 is split into two funds 2a) one fund grows by 3.8% 2b) we're told to set this to X, since it has the smaller growth rate 3) the other fund grows by 6%
We know from basic math that:
1) the fund at 6% has to be the difference between the original amount and X, or 1500 - X 2) when you have a percent increase, it's basically 100% of the original PLUS the increase, or 100% + 3.8% = 103.8% increase for X 3) percentages can be represented as decimals, so 1 + 0.038 = 1.038 4) percent increases MULTIPLIED BY the original amount get you the final amount, or X(1 + 0.038)
