The number of teams who entered in a 3-on-3 charity basketball tournament can be modeled by function T, where x is the number of years since the tournament first started.

T (x) = 4x+24

The entire fee paid by each team to enter the tournament can be modelfied by function F, where x is the number of years since the tournament first started.

F (x) = 5x+45

Which function, R, best represented the total entry fees collected in the xth year since the tournament first started?

A. R (x) = 9x^2+29x+69

B. R (x) = 20x^2+1080

C. R (x) = 20x^2+300x+1080

D. R (x) = 9x+69

Hi There!

The number of teams who entered in a 3-on-3 charity basketball tournament can be modeled by function T, where x is the number of years since the tournament first started.

T (x) = 4x+24

The entire fee paid by each team to enter the tournament can be modelfied by function F, where x is the number of years since the tournament first started.

F (x) = 5x+45

Which function, R, best represented the total entry fees collected in the xth year since the tournament first started?

Answer - D. R (x) = 9x+69

Option D makes the most sense for the following question because since whatever x is multipled by the number thats just added so you just combine like terms and do 24 + 45 = 69.
