First, you’d do 10$ spent on lunch and the 35$ spent on the jeans or pants. You add those together to get 45$. You then subtract that from $134.25. Your answer should be $89.25. Now, divide 89.25 by 12.75 to get 7. 7 shirts!
The answer is 7. If you add everything together that she bought except the 12.75 for the shirts and subtract it from the 134.25 then you have the total that she spent on the shirts so then you divide that number by 12.75 to get the total number of shirts which will be 7.
