Question 791858: Ok I'm studying for my exam and these word problems are killing me.
So the question is: Anthony has $25,000 to invest into two different funds. Fund A earns 4.5% simple interest. Fund B earns 5% simple interest. How much should he invest in Fund A so that he earns $1,175 in simple interest for one year?

I have tried 25000*.045x=1175

I'll get you started

Let x = amount of money to invest in fund A, y = amount of money to invest in fund B

Since he has $25,000 to invest, this means that the two smaller amounts x and y must add to 25000 like so

Solve for y to get

-------------------------------------------------------

Fund A earns 4.5% simple interest, so in one year you'll have 0.045x dollars from fund A

Fund B earns 5% simple interest, so in one year you'll have 0.05y dollars from fund B

You want the total of these two interest results to add to $1175, so that means we can set this up

Plug in

Distribute

Multiply

I'll let you finish up.
