Break the story into small steps and do them in order. Write down the result of each step before you go to the next one.
Example: Ana has 60 dollars, buys 2 books at 12.50 dollars each, then gets 15 dollars. Spent: \(2 \times 12.50 = 25\). Left: \(60 - 25 = 35\). Now: \(35 + 15 = 50\) dollars.
Traps:
Spent \(= 2 \times \$23.75 + 1 \times \$13.75 = \$61.25\). Remaining \(= \$90.25 - \$61.25 = \$29.00\). Plus the gift: \(\$29.00 + \$28.00 = \$57.00\). (Forgetting to add the gift gives $29.00. Subtracting each price only once (not multiplying by the number bought) gives $80.75. Subtracting only the first purchase gives $70.75.)
Total baked \(= 11 \times 24 = 264\) cookies. Remaining \(= 264 - 219 - 5 = 40\) cookies. (Subtracting only the sold cookies gives 45 cookies. Grouping the subtraction as \(264 - (219 - 5)\) gives 50 cookies. Reporting the cookies that are gone (\(219 + 5\)) gives 224 cookies.)
