Start with $30.25.
Subtract $14.00 to isolate the amount of money spent on admission.
30.25-14.00= 16.25. As a group $16.25 was spent on admission.
Admission is 3.25 per person. Divide 16.25 by 3.25.
16.25/3.25=5.

Answer:
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Step-by-step explanation:
0 = – 3x2 – 2x + 6
It can still be written as
– 3x2 – 2x + 6 =0
Quadratic formula=
-b+or-√b^2-4ac/2a
Where
a=-3
b=-2
c=6
x= -(-2)+ or-√(-2)^2-4(-3)(6)/2(-3)
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Part 1:
From the table, in week 1, the price increased by $1.25, in week 2, the price decreased by $3.125, in week 3, the price increased by $0.625 and in week 4, the price increased by $1.5
After the 4 week the change in price is given by 1.25 - 3.125 + 0.625 + 1.5 = 0.25.
Therefore, the price changed over the 4 weeks period by $0.25.
Part 2:
After the 4 week the change in price is given by 1.25 - 3.125 + 0.625 + 1.5 = 0.25.
Therefore, the price increased over the 4 weeks period.
Part 3:
Given that the price of 1 gram of gold was $39.28 at the end of week 4. since the price of 1 gram of gold increased by $0.25 over the 4 weeks period, the price of 1 gram of gold at the beginning of week 1 is given by:
39.28 - 0.25 = $39.03
C. The graph
The equation y=8x should have a slope of 8. This means that it should go up 8 spaces, every time it moves over by 1. but if you look at the graph you’ll see the slope is 1/8 because it goes up 1 space after moving over 8. If the graph were correct, the x and y values would be swapped.
