Required
What does 9m + 3(1.2m) represent
The expression can be split to:
9m and 3(1.2m)
<u>For 9m:</u>
From the question, we understand that:
Multiply both sides by 9
This means that:
9m = the cost of lessons for 9 hours on weekdays
<u>For 3(1.2m):</u>
From the question, we understand that:
Multiply both sides by 3
This means that:
3(1.2m) = the cost of lessons for 3 hours on weekends
Hence, the expression represents:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends
S = the number of student tickets sold a = the number of adult tickets sold The drama class sold 25 more student tickets than adult tickets to the fall play s = a + 25 The class collected $660 from ticket sales: 6s + 3a = 660 divide both sides by 3 2s + a = 220 by solving the system of equations s = a + 25 2s + a = 220 we find s = 81.67 student tickets a = 56.67 adult tickets
