Which strategy best explains how to solve this problem? George entered his frog in a jumping contest. The frog jumped 2 feet the first jump. On the second jump, the frog jumped twice as far (4 feet). Each time the frog jumped, the jump doubled in length from its previous jump. How far did the frog jump on the 5th jump? A. Make a table. In the first row, write 1st jump - 2 ft. In the next row, write 2nd jump - 2 ft. In the 3rd row, write 3rd jump - 2 ft. Continue this pattern until you get to the 5th jump. Then add the numbers in the right column to find the number of feet the frog jumped on the 5th jump. B. Draw a diagram. Draw a line and label it 2 ft. Draw a line twice as long and label it 4 ft. Do this three more times. Keep doubling the distance each time to find how far the frog jumped on the 5th jump. C. Write a number sentence. (2 × 5) + 2 + 4 = x Multiply 2 inches by the 5th jump, then add the distances from the first and second jump.

Miguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, one chip has the number 3, and the other chip has the number 5. Miguel must choose two chips, and if both chips have the same number, he wins $2. If the two chips he chooses have different numbers, he loses $1 (–$1). Let X = the amount of money Miguel will receive or owe. Fill out the missing values in the table. (Hint: The total possible outcomes are six because there are four chips and you are choosing two of them.) Xi 2 –1P(xi) What is Miguel’s expected value from playing the game? Based on the expected value in the previous step, how much money should Miguel expect to win or lose each time he plays? What value should be assigned to choosing two chips with the number 1 to make the game fair? Explain your answer using a complete sentence and/or an equation.

The revenue, in thousands of dollars, that a company earns selling lawnmowers can be modeled by R(x)=90x-x^2 and the company's total profit, in thousands of dollars, after selling x lawnmowers can be modeled by p(x)= -x^2+30x-200 . Which function represents the company's cost, in thousands of dollars, for producing lawnmowers? (Recall that profit equals revenue minus cost.)A) C(x)= -60x^2-200B) C(x)= 60x^2+200C) C(x)=2x+60x^2+200D) C(x)= -2x-60x^2-200
