Look at the problem! What facts do you have? What do you think is missing? Have you seen a similar problem? How is it similar or different?

Integer Problem A widescreen television usually costs $1250. You can get a 30% discount if you buy it today. You must also pay 8% sales tax. How much will the television cost if you buy it today?

1. Write the Relevant Information Cost of TV: $250 Discount: 30% Tax: 8% Question: What would the TV cost?

Make a picture, model or diagram Work Backwards Write an equation ex: n + 2 = 27 Use a Formula Look at your Reference Sheet Look for a PatternMake a table, list, graph or chart Eliminate Consider a simpler case Compute or simplify Guess and Check

2. Plan Write an equation

3. Solve 1250 x.30 = $375 (discount) = x 0.08 = $70 (tax) = $945 (total cost!) Let’s take this one step at a time.

Look Back

First I found the amount of discount and subtracted that from the total. Then I found the tax of the new price and added it to the total. The television has a price of $945 if purchased today.
