Answer:

#$TC=2($5cl)+$10ca+18($gf)#
TC is total cost, cl is clubs for 2, ca is cart, gf is green fees per hole.

Green fees are #($4)/cup# which is #$4# per hole.

Explanation:

They are going to pay for 18 holes of golf, so the total green fees are #18xx($gf)#.

They are going to pay for the rental of 2 sets of golf clubs at #$5# for a total of #2xx$5#

They are going to pay for rental of a golf cart for #$10.#

That gives us the equation below:

#$TC=2($5cl)+$10ca+18($gf)#

Since we know the total cost #$TC=92#, we can solve for #$gf#

#$92=$10+$10+18($gf)#

#$92-$20=18($gf)#

#$72=18($gf)#

#$gf=(cancel($72)4)/cancel($18)#

#gf=$4
