Eric plans to rent a beach house for a week. he has a coupon for 20% off the daily base rate of $200. he will also have to pay an additional $20 a day for utilities. which expression represents the situation? (d represents the number of days) a) 160d b) 176d c) 180d d) 220d

C. 180d.

Step-by-step explanation:

Let d represent the number of days.

We have been given that Eric has a coupon for 20% off the daily base rate of $200.  

To find the daily base rate after discount we need to figure out 80% of $200 as 100%-20%=80%.

Since Eric will also have to pay an additional $20 a day for utilities, so the total cost for one day will be equal to daily base rate after discount plus additional charges.

As cost of one day is $180, therefore, the cost for d days will be 180d and option C is the correct choice.
