adults cost:$8.75
childrens cost:$6.50
senior citizen cost:$6.50
write an expression for the total cost of the three types of tickets.
An expression for the total cost of the three types of tickets is 8.75a+6.50c+6.50s.
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Let a represent the number of adult tickets, c the number of children tickets and s the number of senior citizen tickets.
Here,
Adults ticket cost:$8.75
Children's ticket cost:$6.50
Senior citizen ticket cost:$6.50
Now, 8.75a+6.50c+6.50s
Therefore, the expression to represent the given situation is 8.75a+6.50c+6.50s.

Answer:
($8.75 * a) + ( $6.50 * c) + ( $6.50 * s)
Step-by-step explanation:
The answer is ($8.75 * a) + ( $6.50 * c) + ( $6.50 * s) because it says write an expression for the total cost of the three tickets, while having those variables represent the number of people who purchased those tickets. So
($8.75 * a) + ( $6.50 * c) + ( $6.50 * s)
represent that.
Answer:
x = -12
Step-by-step explanation:
To solve an equation, you want to "undo" what has been done to the variable. Here, it has been multiplied by -1 and that result added to 7. In general, you want to "undo" these operations in reverse order.
First, you need to subtract 7 to undo the addition of 7. Of course, anything you do to one side of the equation is also done to the other side:
7 -x -7 = 19 -7
-x = 12 . . . . . . . . simplify
Now, you want to undo the multiplication by -1. Multiplication (or division) by -1 will take care of that:
(-1)(-x) = (-1)(12)
x = -12 . . . . . . . . simplify
The solution is x = -12.
