Answer:
$13.50
Step-by-step explanation:
The total amount spent $80.50 would be equal to the sum of the price of the ticket bought by the 6 individuals
total cost of the tickets for the 2 younger children = $12.50 x 2 = $25
let the price of each ticket for the three older children be represented by x. the total price of the 3 tickets would be 3x
$80.50 = $25 + 3x + 15
Collect like terms and solve for x
$40.50 = 3x
x = $13.50
Answer:
(1.5, -13.5)
Step-by-step explanation:
Midpoint Formula: 
Simply plug in our coordinates into the formula:
x = (17 - 14)/2
x = 3/2
y = (-11 - 16)/2
y = -27/2
There are 1000 mL in 1 Liter. Therefore, in 250 mL, there are 250/1000 Liters, namely 0.25 Liters.
He had 2 to begin with, so now he has 2 + 0.25 Liters then.
To set the equation,we can first find how much price would be raised within a year:
=500×(1+7%)
=500×1.07
As the years go by the increase would accumulate,and the equation would be:
