Bikes Trikes Wheels Wheels Total 17 10 34 30 64 3. (a) Mr. Akika has 32 18-cent and 29-cent stamps, all told. The stamps are worth $8.07. How many of each kind of 18 9 36 27 63 stamp does he have? (b) Summarize your solution method in one or two carefully written sentences. 4. Toni of Example 1.1 thinks of another number. She then triples it and subtracts 1 1, her result is 28. (a) Use the guess and check strategy to find a solution. (a) Using Guess and Check, what is Toni's number? (b) Complete the table to find a solution. (b) Using Make a Table, what is Toni's number? (c) Find a solution by completing this diagram. (c) Are there other methods to find out Toni's number? (Hint: Try algebra, which we will later use in Section 1.4.) 5. Xin has nine coins with a total value of 48 cents. What coins does Xin have? (Hint: Make an orderly list of the nickels, dimes, pennies, and quarters.) 6. Make up a problem similar to problems 1 and 2. 7. Who am I? If you multiply me by 5 and subtract 8, the result is 52
