Question 7: Dan's at Shades R Us
Shades R Us charges $20 per day to rent a lounge chair and $15 per day to rent an Umbrella. Dan and Lisa paid a total of $245 to rent a lounge chair and an umbrella each during their vacation. Lisa rented the lounge chair and umbrella for 1 day less than Dan. The following equation represents this situation, where \(x\) represents the number of days Dan rented the lounge chair and umbrella.
\[ 20 x + 15 x + 20(x-1)+15(x-1) = 245 \]
What is the total amount Dan paid to rent the lounge chair and umbrella during his vacation?
