The total cost c ( in dollars) to participate in a triathlon series is given by the literal equation c =90x+35 where x is the number of triathlon in which you participate. if your maximum annual triathlon cost is 1000 what is the maximum number of triathlons in who you could prarticipate?

We can participate in 10 triathlons.

Step-by-step explanation:

Total cost C to participate in x number of triathlon is given by the expression

C = 90x + 35

If the maximum cost of the annual triathlon is = $1000

Then we can find the maximum number of triathlons by putting C = $1000 in the expression

1000 = 90x + 35

90x = 1000 - 35

90x = 965

x =

x = 10.72

Therefore, we can participate in 10 triathlons.
