Mixture word problems worksheet for Algebra 1

Algebra 1 mixture problems are practice in setting up one linear equation from a story. Make a small table with the amount, the percent or price, and the total for each part, and multiply across. Coffee blends and nut mixes work the same way as solutions, with dollars in place of percents.

Also taught in Algebra 2, at its own level and with its own examples.

How to do these

How many pounds of peanuts at $2 a pound must be mixed with 6 pounds of cashews at $8 a pound to make a mix worth $4 a pound?

  1. Value of the peanuts: 2x. Value of the cashews: 8 × 6 = 48.
  2. The mix is x + 6 pounds at $4: 2x + 48 = 4(x + 6).
  3. 2x + 48 = 4x + 24, so 2x = 24 and x = 12.

The answer is 12 lb.

Where students go wrong

Forgetting that the total amount includes the unknown. The mix is x + 6 pounds, not 6, so the right side is 4(x + 6); writing 4 × 6 leaves out the peanuts you are adding.

Also called solution problems, concentration problems, acid mixture or percent mixture word problems.

What you can put on this worksheet

Mixture problems
How many milliliters of a 20% alcohol solution must be mixed with 4 milliliters of a 60% solution to make a 30% solution? → 12 milliliters
Mixtures
A shop has 18 pounds of $8.00 cashews. How many pounds of $3.50 peanuts should it add to make a mix worth $7.55 a pound? → 2 lb
Price of a mix, adding water, a missing price or percent
8 lb of walnuts are mixed with 7 lb of peanuts that cost $2/lb. The mix is worth $5/lb. What do the walnuts cost per pound? Round to the nearest cent. → $7.63/lb
Find the unknown percent
A jeweler melts 14 grams of one alloy with 14 grams of an alloy that is 20% silver. The new alloy is 30% silver. What percent silver was the first alloy? → 40%

Questions about these worksheets

Yes. Every mixture word problems sheet is free to print and free to download as a PDF. There is no account to make, no email to hand over and no limit on how many you take.

Yes. The answer key prints on a second page, and you can choose whether it shows each question beside its answer or just the answers in a list.

Yes. Print straight from the page, or download the PDF and print that. The sheet is laid out for paper rather than squeezed off a screen, so there is room to work under each question, and the answer key comes out on its own page.

Algebra 1 is usually taken around 8th or 9th grade, though schools vary and plenty of students meet it earlier or later. Pick the difficulty rather than the grade: the easy level suits a first lesson on it, the hard level suits review before a test.

Yes, as many as you like. The questions are built fresh each time rather than picked from a fixed set of files, so pressing Generate gives a new sheet. That is what you want for a second class, a retake, or two students sitting next to each other.

That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the mixture word problems questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.

Yes. There are three levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.

You pick from 4: mixture problems, mixtures, price of a mix, adding water, a missing price or percent and find the unknown percent. Tick as many as you want and set how many of each, or let it spread them evenly.

Averaging the two percentages. Mixing a 20% and a 50% solution does not give 35% unless the amounts happen to be equal; the strength is pulled toward whichever there is more of.
