Total cost: 3 items
for 3rd grade
Use addition to find out how much the 3 items cost in total
Total cost of 3 items
When you buy things you need to know how much it will cost you so that you know if you have enough money. We use addition to calculate the TOTAL cost by adding up each individual item cost. Adding money is similar to adding any other numbers in math except that if the 3 numbers together add up to more than one dollar then we need to deal with both dollars and cents.
Sometimes we are just adding the cents: Say we have 3 things that cost 22 cents each. To know the total cost, we simply add the 22 cents three times to get 66 cents. If the items cost different amounts, we can still add up those 3 amounts to get a total cost:
15¢ + 23¢ + 34¢ = 72¢.
When the total goes over one dollar, we need to get an answer in both dollars and cents. So if we add 75 cents, 75 cents and 75 cents we have a total of 225 cents but we know that 200 cents is 2 dollars, so we have 2 dollars and a remainder of 25 cents. So the sum with answer is
75¢ + 75¢ + 75¢ = $2.25¢.
