shawn's rentals charges $27.50 per hour to rent a surfboard and a wet suit. darla's surf shop charges $23.25 per hour to rent a surfboard plus $17 extra for a wet suit. for what total number of hours are the charges for shawn's rentals the same as charges for darla's surf shop?
a. 3
b. 4
c. 5
d. 6

OK, here, we can simply apply the values and solve for which one works.

23.50 * 3 = 70.50
23.25(3) + 17 = 86.75

Now, they are not equal.

Try another one!

27.50 * 5 = 137.50
23.25*5 + 17 = 133.25

Not correct either!!

Try another!

27.50 * 6 = 165
23.25 *6 + 17 = 156.50 

NO! Lets try the second one!!

27.50*4 = 110
23.25 * 4 + 17 = 110

THIS ONE IS CORRECT!

4 hours is when they have the same charges. 

What is the last question i don’t see it?

Then just do it (lol)
