Sophie wanted to buy an inflatable pool that cost $42, a camera that cost $34, and a paddle board that cost $18. Rather than bringing the exact amount of money to purchase the items, Sophie wanted to round each number and bring only 10 dollar bills.
If Sophie rounds each price to the nearest 10 dollars and brings that amount, she thinks she will have enough money. Is Sophie correct? If not, how many more 10 dollar bills would Sophie need to bring? Explain your reasoning.
Sophie is incorrect. If she rounds to the nearest 10 dollar bill (40 + 30 + 20), she will bring in $90. However the total cost of all the items is $94 so she would still need $4 more.
She would need to bring in $100 or 10 ten dollar bills to have enough money.
