Adult ticket costs= $46
Children ticket costs= $104
Let x represent the price of adult tickets
Let y represent the price of children tickets
x + y= 150.......equation 1
8x + 3y= 970........equation 2
From equation 1
x= 150 - y
substitute 150-y for x in equation 2
8(150-y) + 3y= 970
1200- 8y + 3y= 970
-8y + 3y= 970-1200
-5y= -230
y= 230/5
y= 46
From equation 1
x + y= 150
x + 46= 150
x= 150 - 46
x= 104
Hence the cost of children tickets is $104 and the cost of adult tickets is $46

Answer:
<em>3 seconds</em>
Step-by-step explanation:
Complete question:
<em>An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled using h(t)=144-16t2. How many seconds will it take the object to reach the ground? 2 seconds 3 seconds 9 seconds 16 seconds</em>
<em></em>
Given the height of an object modelled by the expression;
<em>h(t)=144-16t²</em>
The object will reach the ground when h(t) = 0
Substitute into the formula
0 = 144 - 16t²
-144 = -16t²
144 = 16t²
Swap
16t² = 144
t² = 144/16
t² = 9
Square root both sides
√t² = ±√9
t = ±3secs
<em>Since the time cannot be negative, hence the object will reach the ground 3 seconds after</em>
