"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.
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.

Answer:
$25.98
Step-by-step explanation:
Add the items Sara buys to find the total:
17.50 + 6.50 = 24
Convert 8.25% into a decimal:
8.25/100 = 0.0825
Multiply 0.0825 by 24:
0.0825 x 24 = 1.98
1.98 is the amount of tax, then add the tax to the total amount you got before tax.
24 + 1.98 = 25.98
Your answer would be 25 dollars and 98 cents!
