Question

A video game enthusiast is planning to attend a convention

where the latest technologies, products, and games will be show-
cased. There is a $75 registration fee to attend the convention.
She plans to stay at a hotel with a daily rate of $210 and spend
$30 on meals per day.
Create an equation to represent her expenses for the convention
based on the number of days she will be in attendance. Then,
use your equation to answer the following question.
How much will she spend to attend the convention for 3 days?

Answer 1

240x + 75, $795 for 3 days

Explanation:

$75 is not affected by the number of days she will be there, meanwhile, hotel and meal costs are. So, we will use x to represent the number of days and create an equation.

210x + 30x + 75

Then we can combine like terms

240x + 75

Using our new equation, we can solve for the total cost of 3 days.

240(3) + 75 = 795

3 days will cost $795
