Mal works at a photo gallery. He charges $50 for a large photo and $40 for a large frame. Sales tax is 5%. How much total tax will a customer pay on both?
Answer the questions to show how to write and simplify expressions that represent the problem.
1. One way to calculate the total tax is 0.05(50 + 40). Use the order of operations to evaluate this expression.
2. Use the distributive property to expand 0.05(50 + 40).
3. Find the total tax using the expanded expression. Did you get the same answer as you did by evaluating the original expression?
4. Which expression, the original expression or the expanded expression, involves finding the total cost first, then calculating the tax on that total?
