WALT: solve an algebra question

Today we solved an algebra problem to calculate how much money would be spent and earned by 2 twins. Tom started with 20 dollars and spent 2 dollars per day, starting from Monday. Tia started with 0 dollars and earned 2 dollars 50 per day, also Starting from monday. I used a table to help me calculate the day Tia would overlap Tom with money.We made links to statistics and chose a line graph to show our thinking. You can see clearly that by Friday, Tia had more money than Tom. Thanks for Listening.
