Types of Problems and Solutions
Understanding the types of problems students will encounter in Unit 3 can help them prepare more effectively. Here are some common problem types along with example solutions:
1. Proportional Relationships
Example Problem: A recipe calls for 2 cups of flour for every 3 cups of sugar. If you want to make a larger batch using 10 cups of sugar, how many cups of flour will you need?
Solution:
- Set up the proportion:
\[
\frac{2 \text{ cups flour}}{3 \text{ cups sugar}} = \frac{x \text{ cups flour}}{10 \text{ cups sugar}}
\]
- Cross-multiply to solve for \(x\):
\[
2 \times 10 = 3 \times x \implies 20 = 3x \implies x = \frac{20}{3} \approx 6.67 \text{ cups flour}
\]
2. Algebraic Expressions
Example Problem: Simplify the expression \(3(x + 4) - 2(x - 1)\).
Solution:
- Distribute:
\[
3x + 12 - 2x + 2
\]
- Combine like terms:
\[
3x - 2x + 12 + 2 = x + 14
\]
3. Solving Inequalities
Example Problem: Solve the inequality \(3x - 5 < 4\).
Solution:
- Add 5 to both sides:
\[
3x < 9
\]
- Divide by 3:
\[
x < 3
\]
4. Percent Problems
Example Problem: A shirt originally costs $50. During a sale, it is discounted by 20%. What is the sale price?
Solution:
- Calculate the discount:
\[
20\% \text{ of } 50 = 0.20 \times 50 = 10
\]
- Subtract the discount from the original price:
\[
50 - 10 = 40
\]
- The sale price is $40.
