Samantha buys one vase and x roses. The vase costs $15 and each rose costs $2.

What function equation represents the amount of money Samantha spends?

f (x) = 15x-2

f (x) = 2x-15

f (x) = 2x+15

f (x) = 15x+2

I believe the correct answer from the choices listed above is the third option. The equation that would represent the amount of money Samantha spends would be f (x) = 2x+15 where 15 represents the value of the vase which is a fix amount and 2x is the value of the roses.

Hope this answers the question. Have a nice day.
