I admit I have made the “you’ll never use algebra” crack myself. But I knew that wasn’t true and here is the best defense of it. (thanks Dr. Helen)

But now I can honestly say that they will need Algebra someday! I made roast chicken for dinner today. When I checked the recipe on the chicken wrapping, it said to roast a 3.5 lb. chicken for 1.5 hours. But my chicken weighed 4.7 lbs. What to do?

Easy! Just set up this formula: 1.5 = X

3.5 4.7

Cross-multiply: 3.5X = 7.05

Divide both sides by 3.5 and you end up with X=2.01

I roasted the chicken for two hours and it came out just right 🙂
