22. Kofi borrowed GH₵50 from his friend. He then spent GH₵30 on food and earned GH₵20 from a job. Which expression correctly represents his financial situation? Step 1: Represent each financial transaction with a signed number. • Borrowing GH₵50 means a debt, so it's represented as -50. • Spending GH₵30 means a decrease in money, so it's represented as -30. • Earning GH₵20 means an increase in money, so it's represented as +20. Step 2: Combine these values into a single expression. The financial situation is the sum of these transactions: -50 - 30 + 20 This matches option B. The final answer is B. -50 - 30 + 20. 23. Two numbers have a ratio of 5:3. If their sum is 40, what is the larger number? Step 1: Represent the two numbers using the given ratio. Let the two numbers be 5x and 3x, where x is a common multiplier. Step 2: Set up an equation using their sum. The sum of the two numbers is 40: 5x + 3x = 40 Step 3: Solve for x. 8x = 40 x = (40)/(8) x = 5 Step 4: Find the larger number. The two numbers are 5x and 3x. The first number is 5 × 5 = 25. The second number is 3 × 5 = 15. The larger number is 25. The final answer is C. 25. What's next?
