If 2 pencils cost 50 cents, how much do 10 pencils cost?

Step 1: Identify the cost of 2 pencils, which is 50 cents.
Step 2: Determine how many times more pencils we want. We want 10 pencils, and 10 is 5 times more than 2 (because 10 divided by 2 equals 5).
Step 3: Multiply the cost of 2 pencils (50 cents) by the number of times more pencils we want (5).
Step 4: Calculate 5 times 50 cents, which equals 250 cents.
Step 5: Convert 250 cents to dollars. Since 100 cents equals 1 dollar, 250 cents equals 2 dollars and 50 cents.
