Question

Keisha bought 10 tickets to a concert. She paid an 8% service charge for buying them online. Her total cost was $237.60. What equation can be used to model the total cost of the tickets?

Answer 1

To model the total cost of the tickets, we can use the equation: Total cost = Ticket price × Number of tickets + Service charge.

Step-by-step explanation:

To model the total cost of the tickets, we can use the equation:

Total cost = Ticket price × Number of tickets + Service charge

Given that Keisha bought 10 tickets and paid an 8% service charge, we can substitute the values into the equation:

Total cost = Ticket price × 10 + 0.08 × Total cost = $237.60

Then, we can solve for Ticket price:

10 × Ticket price + 0.08 × Total cost = $237.60

Equations are mathematical statements that assert the equality of two expressions. They typically contain variables, constants, and mathematical operations like addition, subtraction, multiplication, division, exponents, and more. Equations are solved to find the value(s) of the variables that satisfy the equality.
