Explanation:

Question 1

To measure the amount of matter (mass) in a small object like a pushpin, grams are appropriate because kilograms are used for much larger masses. A pushpin is light, so grams (A) are the correct unit.

Step1: Convert coins to dollars

1 dime = $0.10$, so 6 dimes = $6\times0.10 = 0.60$ dollars.
1 nickel = $0.05$ dollars.
1 penny = $0.01$ dollars, so 5 pennies = $5\times0.01 = 0.05$ dollars.

Step2: Sum the earned money

Earned money = $0.60 + 0.05 + 0.05 = 0.70$ dollars.

Step3: Add to initial money

Initial money = $1.50$, so total = $1.50 + 0.70 = 2.20$ dollars.

Step1: Find wins for Cardinals and Lions

From the bar graph:

• Lions' wins: Let's assume the Lions' bar reaches up to 2 (from the y - axis labels).
• Cardinals' wins: Let's assume the Cardinals' bar reaches up to 10 (from the y - axis labels).

Step2: Calculate the difference

Difference = Cardinals' wins - Lions' wins = $10 - 2 = 8$.

Answer:

A. grams
