1. Six students brought money for the school field trip to Flagler’s Museum. Their teacher plotted the smallest and largest amounts of money brought by the students. Let m represent the money brought by the students. Based on the graph above, which inequality best describes the range of possible values of m ? 3 4 5 6 7 8 9 10 Since the circle is closed, then m must be greater or equal to 4… …and less then or equal to 9.5.

2. A baseball player’s batting average can be determined using the following equation where a represents the batting average, n, represents the number of at bats, and h, represents the number of hits. What would be a player’s batting average if he had 40 at bats and had 18 hits? Use the given formula…substitute 40 at bats for n and 18 hits for h and calculate his average…

3. The average speed that you drive on a trip can be determined using the formula: Where d represents distance traveled, r represents the rate of speed, and t represents the time traveled. If you drove 520 miles in 8 hours, what was the average speed at which you traveled? Use the given formula…substitute 520 miles for d and 8 hours for t and calculate the rate of speed… Divide each side of the equation by 8…

4. Evan wants to buy tokens to play video games at the local arcade. He already has 18 tokens left over from his last visit. For each dollar that Evan puts into the token machine, he receives 16 tokens. The equation below can be used to determine the total number of tokens Evan will start with based on d, dollars that he brings with him to the arcade. How many tokens will Evan have if he brings 3 dollars to the arcade? Use the given formula…substitute 3 dollars for d, use PEMDAS to solve the equation for t, tokens 6

5. Pets-R-Us sells fish for freshwater aquariums. They sell Tiger Barbs for $0.95 each and Goldfish for $0.65 each. The equation below can be used to determine how much money Heidi, h, will spend on fish, where t represents Tiger Barbs and g represents Goldfish. How much will Heidi spend if she buys 6 Goldfish and 3 Tiger Barbs? Use the given formula…substitute 3 for t (Tiger Barbs) and 6 for g (Goldfish) use PEMDAS to solve for the total Heidi spends… 6. 7 5
