Billy has a gift card with a $150 balance. He buys several video games that cost $35 each. After the purchases, his gift card balance was $45. Find how many video games Billy brought.
$150-$45=$105 $105÷$35(which is how much each video game cost) which equals 3 video game. When you times the 3 with 35 it equals 105. So, when you subtract 150 with 105 it equals 45(the balance) (I'm not good at explaining, sorry if can't understand)
