  2. Coin & Number Word Problems I can write and solvesystems of linear equations word problems. Don’t forget to write this “I Can” in your target sheet.

  3. Coin & Number Word Problems The sum of two numbers is 45, their difference is 7. Find the smaller of the two numbers. Ex 1. 1. Define your variables. Let x be one of the numbers and y be the other. 2. Create your equations. 3. Solve using elimination. + 4. Substitute to find other variable. 5. Answer the question. The smaller number is 19.

  4. Ex 2. A jar of nickels and dimes contains $8.60. There are 4 more nickels than dimes. How many of each coin is there? How much is a nickel worth? A dime? 1. Define your variables.

  5. Ex 3. Julia smashed a piggy bank and found $13.00 worth of nickels and quarters. There were 132 coins in all. How many quarters were there? How much is a nickel worth? A quarter? 1. Define your variables. Let x = # of nickels and y = # of quarters. Nickel is worth $0.05 and a quarter is worth $0.25 2. Create your “money” equation. 3. Create your “# of each” equation. 4. Solve using any method. + 5. Answer the question. There are 32 quarters in the piggy bank.
