Given:$7/child
$10/adult
Total people = 700
Total money = $6,400
First, make two equations.
Let a = # of adults & Let c = # of children.
Let p = total people
1. a+c = 700
2. 10a+7c = 6,400
Then, rearrange the equation to solve for a variable.
c = 700-a
Substitute (700-a) for c, or the # of children in the second equation.
10a+(700-a) = 6400
9a+700 = 6400
9a+700-700 = 6400-700
9a = 5700
9a/9 = 5700/9
a = 633
= # of adults attended700-633

= c =
66
= # of children attended
Answer and Step-by-step explanation:
1. slope intercept
2. point-slope form
3. standard
Explanation:
1.
A <u>slope intercept form</u> equation is when it's set up as y = m x + b
m = slope
b = y-intercept
2. <u>A point-slope form</u> is when a line passes through a point
and the equation is set up as y
−b = m (
x−a)
m = slope
(a, b) A point that the line passes through
3. <u>standard lope form</u> is when the equation is set up as
Ax + By = C
