Answer:
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 = [tex]\frac{965}{90}[/tex]
x = 10.72
Therefore, we can participate in 10 triathlons.
