Write Algebraic Expression in x
Kim invests \$22,000, some in stocks and the rest in bonds.

Let x = amount invested in stocks.

Write an algebraic expression in x for "the amount invested in bonds."

...Why not have an attempt yourself?

\$22,000 is spent. x is spent on stocks. Everything that's left over is spent in bonds.

How much is spent in bonds?

Let B = everything that's left over is spent in bonds.

B - (x + 22,000).

Is this the correct expression?

You've overcomplicated this.

She starts with $22,000$. Then she spends $x$ on stocks.

At this point, she has $22,000 - x$ left.

If you let B equal the amount spent on Bonds, $B = 22,000 - x$
