Unit Equations

Step 1. Read the problem carefully.

Step 2. What are you trying to find- I am trying to find the cost of 5 items/objects and use different types of solutions.

Step 3. Important Information.

1. Windows 7 Ultimate. Cost-$399.99. Quantity- 3. 2. Microsoft Zune 32GB. Cost- $249. Quantity- 2. 3. Xbox 360 Final Fantasy Bundle get Assassin’s Creed 2. Cost-$399.99.

Quantity-3.

4. Play Station 3. Cost- $297. Quantity- 2. 5. MacBook Pro 15inch. Cost-$1,699. Quantity- 1.

Step 4: Decide what method are you going to use- multiplications formula. Step 5: Solve the question. 1. $399.99 X 3 = x. x= $1,199.97 2. $249 X 2 = d. d= $498 3. $399.99 X 3 = x. x=1,199,97 4. $297 x 2 = x. x= $594

Step 6: Check if answers are right-yes.

Reflection

I think that this investigation was easy because we did the investigation on the computer and on excel. In excel there is auto sum so we don’t need to do the calculations ourselves. But when I was doing it, the formulas are the same as writing it. Some of the terms like algebraic terms are unknown to the computer so we have to write them in. Pro numerals as well are not in the computer.
