Answer:
35 tickets at $35, 72 tickets at $25
Step-by-step explanation:
x+y=107 -> 5x+5y=535
45x+25y=3375
simplify, divide by 5 to get
9x+5y=675
Substract
9x+5y=675
- 5x+5y=535
4x=140 -> x=35
y=107-35 = 72
I'm afraid it's not 11 (unless you can round the result up, but there is no mention about it).
8 + 13 + 11 + 9 + 13 = 54
54 / 5 = 10,8
Firstly you sum all the numbers and then you divide the result by the amount of the summed up numbers.
Answer:
Step-by-step explanation:
x + 25 + 4x + 10 = 180
5x + 35 = 180
5x = 145
x = 29
<1 = 29 + 25 = 54
<2= 4(29) + 10 = 116 + 10 = 126
