Step 1

Given,

Vonna scored 75 goals in her soccer kicking practice.

Her succes - to - failure rate is 5:4

Let, total number of successful attempts of Vonna \(\displaystyle={5}{x}\)

and, total number of unsuccessful attempts of Vonna \(\displaystyle={4}{x}\)

Step 2

According to the question,

\(\displaystyle{5}{x}={75}\)

\(\displaystyle\Rightarrow{x}={\frac{{{75}}}{{{5}}}}={15}\)

Total goals attempted by Vonna \(\displaystyle={5}{x}+{4}{x}={9}{x}={9}\times{15}={135}\).

Vonna attempted a total of 135 goals.
