  1. Writing Algebraic Expressions to Solve Word Problems. How many minutes in 1 hour, 14 hours, in "n" hours?

  2. Algebra is used every day to solve everyday problems. • For example: • You have a job and you get paid $8.25 an hour. • You want to figure out how much pay you will receive if you worked 16 hours.

  3. You can write in words, I get paid $8.25 for every hour I work. • Algebraically, you would write: • $8.25h • which means 8.25TIMES the number of hours you worked.

  4. You should always write the formula FIRST for every question • SO, you would write • $8.25h = pay • Then, substitute the number of hours into the formula. • $8.25(16) = p (pay) • Calculate the result • Your pay would be$132.00 • Write your answer asp = $132.00

  5. Now it’s your turn. • Using the formula, calculate your pay if you worked: • 20 hours? • 32 hours? • 18.5 hours? • 22 hours? • 110 hours? Every question must start with the formula $8.25h = p Then substitute into the formula the hours that you worked. Remember the answer is MONEY and should be in that form!
