Question

LaToya decides to join a gym for a minimum of one month to train for a triathlon. The gym charges a beginner's fee of $100 and a monthly fee of $38. If x represents the number of months that LaToya is a member of the gym, the equation below can be used to determine C, her total membership fee for that duration of time.

100 + 38x = C

LaToya has allocated a maximum of $404 to spend on her gym membership. Which number line shows the possible number of months that LaToya can be a member of the gym?

I think its A? but im not sure, number lines always mess me up...

Answer 2

\[100+38x\leq 408\]
\[38x\leq 308\]
\[x\leq 308\div 38\] and
\[308\div 38=8.10...\] so you are right. between zero and 8
