Answer:
Step-by-step explanation:
a = adult cost
c = child cost
a = c + $3
200a + 100c =$2100
^ each # of tickets sold
200(c+3) + 100c =$2100
200c + 600 + 100 c = 2100 combine like terms
300c + 600 = 2100 need variable only on one side of equal sign so you subtract 600 from each side of the = sign
300c = 1500 now divide by 300 on both sides to isolate variable
c = $5
In this item, we are given with the slope, m = 2/3 and intercept of (1,1). The equation of the line that contains these properties is,
y - y₁ = m(x - x₁)
Substituting the known values,
y - 1 = (2/3)(x - 1)
Simplifying,
3y - 3 = 2x - 2
Further simplifying,
<em> 2x - 3y = -1</em>
