22-(7+5) = 10
10-3 = 7
X=7
Answer:
350 adult tickets were sold.
Step-by-step explanation:
Let's set up some values:
x = adult tickets
x + 50 = student tickets, since there were 50 more student tickets than adult tickets.
Now, let's set up our equation. If these two values add up to 750 tickets, then we can conclude the following:
(x) + (x + 50) = 750
2x + 50 = 750
2x = 700
x = 350 adult tickets. This means there were 400 student tickets sold.
Total triathlon distance →1.5 km + 40km + 10 km = 51.5 km
So 51.5 km represents 100% of distance covered.
The % of each component = (distance of component/Total distance) multiplied by 100% so :
% of swim → (1.5 / 51.5) × 100 → 0.029 × 100 = 2.9%
% of bike ride → (40 / 51.5) × 100 →0.776 × 100 = 77.6%
% of run → (10 / 51.5) × 100 → 0.194 × 100 = 19.4%
Percentage spent on land will be
(40 km bike ride + 10 km run / Total triathlon distance) multiplied by 100%
(50 / 51.5) × 100 → 0.970 ×100 = 97%
