WHO CAN BUY A TICKET?
Four friends want to see a show. Each friend brings a bag full of coins to pay for a ticket. A ticket costs $20. (Hint: $20 = 2,000 cents)
Which of the friends has enough money to buy a ticket?
Answer:
Penny, Dmitri and Carter has enough cents to purchase the ticket.
Explanation:
Cost of the ticket = $20 = 2000 cents.
Number of pennies Penny gets = 2316.
Number of nickels Nicki gets = 382.
Number of dimes Dmitri gets = 217.
Number of quarters Carter gets = 83.
Conversion:
1 penny = cent.
=> Number of pennies Penny gets = 2316 × 1 = 2316 cents.
1 nickel = 5 cents.
=> Number of nickels Nicki gets = 382 × 5 = 1910 cents.
1 dime = 10 cents.
=> Number of dimes Dmitri gets = 217 × 10 = 2170 cents.
1 quarter = 25 cents.
=> Number of quarters Carter gets = 83 × 25 = 2075 cents.
