Liam had 83 cents. Then he spent one dime and two pennies. How much does he have now?
This is a two-step problem. First, we need to work out how much money Liam spent, what is one dime and two pennies. Then, we need to work out how much change Liam would have from his 83 cents if he spent a dime and two pennies. Once we’ve worked out how much Liam spent, we need to take this amount from 83 cents.
We know that Liam spent a dime. One dime is equal to 10 cents. Liam also spent two pennies. And we know that two pennies are equal to two cents. Now, we can calculate the first step of our problem. Liam spent 10 cents and two cents. What is 10 plus two? 12 cents. We know that Liam had 83 cents to begin with. And now, we know that he spent 12 of them. So, we need to calculate 83 cents take away 12 cents.
Let’s start by taking away the ones. Three ones, or three cents, take away two cents leaves us with one cent. Now, we need to subtract in the tens column. We have eight 10s, or 80 cents. And we need to take away one 10, or 10 cents. What is eight take away one? The answer is seven. If Liam had 83 cents, and he spent a dime and two pennies, he will have 71 cents now. A dime and two pennies is equal to 12 cents. We took 12 from 83 to give us our answer of 71 cents.
