Can someone help me figure out the equation? I am not good at figuring this out.

Investing her bonus. Donna invested her $33,000 bonus and received a total of $970 in interest after 1 year. If part of the money returned 4% & the remainder 2.25%, how much did she invest at each rate?

x = interest at 4% so

interest at4% = 0.04x

How much money is left if we take away x? It is 33,000-x. That was invested at 2.25% so

interest earned at 2.25% =

0.0225(33,000-x).

If we sum the two interest amounts we have $970.

amt at 4% + amt at 2.25% = 970.

Just substitute and solve for x.

Post your work if you get stuck.

No, I think you dropped the 0.04x but everything else is ok.

0.04x + 0.0225(33,000-x)=970

0.04x + 742.50 - 0.0225x = 970

I'll let you finish.
