The expression representing the total number of quarters is \( 40 + (40 \times 0.20) \) (Option C). After spending 25% of the quarters, you have $9 left.

Solución

Step 1: You start with 40 quarters. Step 2: You find 20% more quarters. This means you add 20% of 40:   20% of 40 = 40 × 0.20 = 8. So, the total quarters now = 40 + 8 = 48. The expression representing this is 40 + (40 × 0.20) which corresponds to answer C. Step 3: You then spend 25% of your 48 quarters. The remaining quarters = 75% of 48:   0.75 × 48 = 36 quarters. Step 4: Each quarter is worth $0.25, so the amount of money left in dollars is:   36 × 0.25 = $9. Final Answers: - The expression representing the total number of quarters is: 40 + (40 × 0.20) [Option C]. - You have $9 left after shopping.

To find the total number of quarters after discovering \(20\%\) more, you start with \(40\) quarters. The expression to represent the total number of quarters you'll take shopping is \(40 + (40 \times 0.20)\), which is \(40 + 8 = 48\) quarters. So, the correct answer is **C**. Now, after shopping, if you spend \(25\%\) of \(48\) quarters, that would be \(12\) quarters. You then have \(48 - 12 = 36\) quarters left. In terms of dollars, since each quarter is worth \(0.25\), you have \(36 \times 0.25 = \$9.00\) left to enjoy!
