ACCUPLACER Elementary Algebra focuses on assessing and enhancing foundational algebra skills essential for success in higher-level mathematics.
Recipes need to be adjusted for different numbers of people. Algebra helps you scale up or down by writing and solving proportions.
Use ratios and set up cross-multiplication to find the new amounts.
Scaling recipes, mixing drinks, or even mixing paint all use these algebra skills.
A recipe for 4 needs 2 eggs. For 8 servings, set up \( 2/4 = x/8 \) and solve for \( x = 4 \) eggs.
If you need 3 cups of flour for 6 cookies, for 12 cookies you’ll need \( 3 \times 2 = 6 \) cups.
