"In Grade 2 and early in Grade 3, students learned to use bar models to solve two-step problems involving addition and subtraction. This is extended in this chapter to include multiplication and division.

<span>Both multiplication and division are based on the concept of equal groups, or the part-part-whole concept, where each equal group is one part of the whole. In Grade 2, students showed this with one long bar (the whole) divided up into equal-sized parts, or units. This unitary bar model represents situations such as basket of apples being grouped equally into bags." </span>https://www.sophia.org/tutorials/math-in-focus-chapter-9-bar-modeling-with-multipli

Ok so the total amount the mom paid is 50.50. It says she bought 10 journals at 2.50 each so subtract 25 which leaves 25.50. Then it says 2 markers at 5 each so subtract 10 which leaves 15.50. Then it states she paid 4.10 in annoying sales tax. So subtract 4.10 and you get 11.40 which is the remaining, which means thatbis how much she spent on a mouse.
