Respuesta :
The equation is modeled as y = 4x + 8z. Then the total money y made in ticket sales will be $80.
What is a linear equation?
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
Tickets for a play cost $4 for each child and $8 for each adult.
Let x be the number of the children's tickets, z be the number of the adult's tickets, and y be the total cost.
Then the equation of the total cost is given as,
y = 4x + 8z
If there are only 20 children's tickets sold.
Then the total money y is made in ticket sales will be
y = 4 × 20 + 8 × 0
y = $80
Thus, the total money y made in ticket sales will be $80.
