Operations with Rational Numbers

The video tutorial explains how 7th grade students at Mathvillie Middle School are selling t-shirts as a fundraiser. The t-shirts cost $3 each to make and are sold for $10 each. The tutorial demonstrates how to calculate the profit from selling 150 t-shirts using the order of operations (PEMDAS). It involves replacing the variable x with 150, performing multiplication, and then addition and subtraction to find the final profit of $1,050.
