Question

The cost y (in dollars) to rent a lane at the bowling alley is proportional to the number x of hours that you rent the lane. It costs $18 to rent the lane for 2 hours.
a) Write an equation that represents the situation
b) Interpret the slope
c)How much does it cost to rent the lane for 3 hours?

Answer 1

Answer:

a) y = 9x

b) For every increase of 1 hour the price to rent the lane increases by $9.

c) $27

Step-by-step explanation:

a) Since it costs $18 for 2 hours we can infer that for every 1 hour it costs $9.

So, the equation would look like this:

y = 9x

b) In this context, for every increase of 1 hour the price to rent the lane increases by $9. Like the question gave us, the price for 2 hours cost $18.

c) Plug 3 into the equation:

y = 9(3)

y = 27

Therefore, it costs $27 to rent the lane for 3 hours.

I hope this helps!!

Answer 2

A) Y=9x
B) m=y/x
M= 18/2
M=9/1

For every a hour you pay 9$ (which btw is bull)

C) 27$

Initial cost x hours or

3(x)=y
3(9)=y
27=y (that’s the same thing as y=27)
