Substitute the x and y values from (3,2).
Formula: y=mx+b
2= 3(3)+b
2-9= -7
y=3x-7
Simply add in the known information. To find the cost of 1700 key chains, substitute it for p in the equation, like this: C=205.00+0.70(1700) and solve.

Step-by-step explanation:
Answer:
Adult price for tour is $16 and Student price for tour is $9.
Step-by-step explanation:
Let the Cost of Adult be x.
Let the Cost of Student be y.
Now Given:
2 adults and 5 students in one van paid $77.
Hence the equation can be framed as;

Also Given;
2 adults and 7 students in one van paid $95.
Hence the equation can be framed as;

Now Subtracting equation 1 from equation 2 we get;

Now Substituting the value of x in equation 1 we get;

Hence Adult price for tour is $16 and Student price for tour is $9.
Answer:
y = 5x
Step-by-step explanation:
Use the direct variation equation y = kx
Plug in 30 as y and 6 as x, then solve for k
y = kx
30 = k(6)
5 = k
Plug in 5 as k into y = kx
y = 5x
So, the equation relating x and y is y = 5x
