Answer:
You sold 20 student tickets.
Step-by-step explanation:
Given that:
Total tickets sold = 27
Total amount collected = $170
Cost of student ticket = $5
Cost of adult ticket = $10
Let,
x be the number of students tickets sold
y be the number of adult tickets sold
x+y = 27 Eqn 1
5x+10y=170 Eqn 2
Multiplying Eqn 1 by 10
10(x+y=27)
10x+10y=270 Eqn 3
Subtracting Eqn 2 from Eqn 3
(10x+10y)-(5x+10y)=270-170
10x+10y-5x-10y=100
5x=100
Dividing both sides by 5
Hence,
You sold 20 student tickets.
To determine the answer to this item, we just have to calculate for the length of the sides of the cube.
Cube 1: Side = sqrt(480/6) = 4 sqrt(5)
Cube 2: Side = sqrt(270/6) = 3 sqrt (5)
We divide both sides to get the answer which is equal to 4/3.
Answer:
Original cost = $16.40
Tax=9℅
Tip=20℅
Total cost is,
=16.40+ 16.40×9℅+ 16.40×20℅
=16.40 +16.40×9 /100+16.40×20 /100
= 16.40+1.476+3.28
=$21.156
