Part B For this part define s and a as follows:

S= number of students tickets purchased
A= number of adult tickets purchased

The total of all tickets sold was $625.00. Write an equation in items like of s and a to represent this information

Part C for this part define a and a as follows:

S= number of adult tickets purchased
A=number of adults tickets purchased

The total number of students and adults who bought tickets is 165. Write an equation in terms of a and a to represent this information.

Part D
Using the information in parts (b) and (c), determine the following:

The number of students who bought tickets

The number of adults who bought tickets

b

step-by-step explanation:

b

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

the answer is $42.96
