Question

Eric wants to rent a bike for the weekend. Biking Shack charges a fee of $21 to rent one plus $6 per day. Bike Nation charges a fee of $12 to rent a pair plus $9 per day. When will the two companies charge the same amount and what will that price be?
Thank you in advance!

Answer 1

Answer: 3 days in they will bot charge 39$

Step-by-step explanation:

Biking shack= 21+6d(d for days)

Bike nation=12+9d

to figure it out lets plug in 1 day for each so for shack that is 29 dollars. for nation that is 21 dollars. now 2 days shack is 33. 2 days for nation is 30. now try 3 days and for shack that is 39 dollars. for nation it is also 39! so there is your answer, 3 days in and they will both cost 39 dollars, hope this helps! :)
