Total cost of 2 items
Learn how to add money costs with this topic
When you buy things you need to know how much it will cost you so that you know if you have enough money to pay for them. So we use addition to calculate the TOTAL cost by adding up each item cost. Adding money is similar to adding any other numbers in math except you have to take care of converting from coins to notes.
For instance, if I went and bought 2 things at 90 cents each, what would the total cost of the items be?
90¢ + 90¢ = 180¢ = $1.80
So when the total goes over one dollar, we need to get an answer in both dollars and cents. So if we add 90 cents and 90 cents we have a total of 180 cents but we know that 100 cents is 1 dollar, so we have 1 dollar and a remainder of 80 cents.
