The swimming team has competed in 45 races this season. They have won 30 races so far. How many races will the team need to win
tatuchka [14]

Answer:

15 races

Step-by-step explanation:

The team has competed in 45 and has won 30. So the success rate is:

Success rate is:

Sccess\ rate=r= \frac{30}{45}*100\\ =66.7\ percent

We have to find the number of races the team needs to win for 75% success rate

Which means that

r = \frac{30+x}{45+x} = 0.75\\

We have to solve the equation for x

\frac{30+x}{45+x}=0.75\\ 30+x = 0.75(45+x)\\30+x=33.75+0.75x\\x-0.75x=33.75-30\\0.25x=3.75\\x=\frac{3.75}{0.25}\\ x=15

The team needs to win 15 races to get 75% success rate ..
