  2. Algebra 1 – Unit 2 Review • Mrs. Fox wants to take her children to Hartford Stage to see a play. Tickets cost $55 per person, there is a handling fee of $2.00 per ticket and a parking voucher will cost $6.50. If she spends $405.50 for tickets, handling fees, and parking, how many tickets did she buy? • Define your variables, write an equation, and solve it to determine the number of tickets that Mrs. Fox bought.

  3. Algebra 1 – Unit 2 Review ANSWER • Mrs. Fox wants to take her children to Hartford Stage to see a play. Tickets cost $55 per person, there is a handling fee of $2.00 per ticket and a parking voucher will cost $6.50. If she spends $405.50 for tickets, handling fees, and parking, how many tickets did she buy? • Define your variables, write an equation, and solve it to determine the number of tickets that Mrs. Fox bought. let t = number of tickets (55 + 2)t + 6.50 = 405.50 t = 7 tickets

  4. Algebra 1 – Unit 2 Review • Phyllis the plumber is a busy lady. For service calls to homes she uses the following formula to figure out how much to charge for her labor (materials are extra of course): • c = 40n + 60 • where c is the amount she charges and n is the number of hours she works. • What is the meaning of 40 in the formula above? • What is the meaning of 60 in the formula above?

  8. Algebra 1 – Unit 2 Review • Solve the following equation. Justify each step. • x + 6x + 38 = 2(5x + 10)

  9. Algebra 1 – Unit 2 Review ANSWER • Solve the following equation. Justify each step. • x+ 6x + 38 = 2(5x + 10) • x + 6x + 38= 10x + 20 distributive property • 7x + 38= 10x + 20 combining like terms • 7x + -7x + 38= 10x – 7x + 20 subtraction property of = • 38= 3x + 20 • 38 – 20 = 3x+ 20 – 20 subtraction property of = • 18 = 3x • 18/3 = 3x/3 division property of = • 6 = x • x = 6
