1. 7.EE.3 Solve real-life and mathematical problems using numerical and algebraic expressions and equations. Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.

2. Briana biked 2.82 miles on Monday, 3.75 miles on Wednesday, and 2.13 miles on Friday. Which statement correctly compares an estimate of the total distance with the exact total distance that Briana biked? A.The estimate 2 + 3 + 2 is smaller than the exact answer but is within 1 mile. B.The estimate 2 + 4 + 2 is greater than the exact answer but is within 1 mile. C.The estimate 3 + 4 + 2 is smaller than the exact answer but is within 1 mile. D.The estimate 3 + 4 + 2 is greater than the exact answer but is within 1 mile.

3. A.The estimate 4 x 7 is larger than the exact answer and is within 1 square inch B.The estimate 4 x 7 is smaller than the exact answer and is within 1 square inch. C.The estimate 4 x 6 + 1 is larger than the exact answer and is within 1 square inch. D.The estimate 4 x 6 + 1 is smaller than the exact answer and is within 1 square inch.

5. You are designing an invitation on a piece of paper that is 8.5 by 11 inches and has a design printed on 2.4 inches on the left and right sides of the paper. How much room is left for your invitation details?

6. Ben and his sister have $40 to go to the movies. Tickets are $10.25 each. Ben will spend 2/3 of the remaining money on food. How much food money will Ben and his sister have?

8. Chad makes $46.50 dollars an hour and will get a 20% raise next week. 1/3 of his income goes to taxes. Do you agree or disagree A.Next week Chad will have 120% increase of his original wage B.Chad’s new hourly wage can be found by 46.50 x 1.20 C. Chad’s new hourly wage can be found by 46.50 +.20(46.5)

9. David is saving money for a car. He has saved $2,700 which is 60 % of the cost of the car. What is the cost of the car? If he saves $125 a week, how many weeks will he need to work to buy the car?

10. Sale Prices: Max bought 2 items that were on sale. One item was 10% off. One item was 20% off. Max says he saved 15% altogether. Could Max be right? Could Max be wrong? Explain.
