Hello, Jonboy!

For the first one, your equation is correct.

Your algebra must have been off . . .

The Quik Mart has two kinds of nuts.

Pecans sell for $1.55 per pound and walnuts sell for $1.95 per pound.

How many pounds of walnuts must be added to 15 pounds of pecans

to make a mixture that sells for $1.75 per pound?

I came up with the equation: . . . . . Right!

And I got x to be 2.5 . . . . no

You should have: .

Then: .

This is the easier of the two problems . . .Alice Gleason invested a portion of $32,000 at 9% interest and the balance at 11% interest.

How much did she invest at each rate if her total income from both investments are $3,200?

Let = amount invested at 9%.

. . It earned: . dollars.

Then = amount invested at 11%.

. . It earned: . dollars.

The total earnings was $3,200.

There is our equation! . . .
