Answer:
T = 5 * ((7 * 10) + (6 * 9) + (3 * 2))
Step-by-step explanation:
The following mathematical expression would calculate the total number of materials in all of the classes which would be represented by the variable T. We would first multiply the quantity of a specific material in a single box by the number of boxes that exist for each separate material and then multiply that number by 5 since there are a total of 5 classrooms and all have the same quantity of the same materials.
T = 5 * ((7 * 10) + (6 * 9) + (3 * 2))
If we were to solve this we would see that there are a total of
T = 5 * ((7 * 10) + (6 * 9) + (3 * 2))
T = 5 * (70 + 54 + 6)
T = 5 * 130
T = 650
650 materials
