J.F. Antona

2 Reading word problems and translate them into algebra terms)
Rules: 1.- Read the problem 2.- Read the problem 3.- Read only the questions and set x and y and write what they are 4.-Read only one sentence and establish the equation (go to the next sentence and do the same…) 5.-Solve the problem.

3 1.- A word problem Tickets at a football match cost $8, $15 or $20 each. The number of $15 tickets sold was double the number or $8 tickets sold more $20 $20 tickets were sold than $15 tickets. If the total gate receipts were $783000, how many of each type of ticket was sold? X= number of $8 tickets Y= number of $15 tickets Z= number of $20 tickets Y = 2X Z= Y 8X+15Y+20Z=783000 4.-Read only one sentence and establish the equation (go to the next sentence and do the same…) 1.- Read the problem 2.- Read the problem 3.- Read only the questions and set x and y and write what they are 5.-Solve the problem (but that is another question). THE END for this moment. (REPEAT THE PRESENTATION IF YOU NEED IT)
