The number of goals scored by a soccer team varies directly as the number of shots on goal. If the Lakeside Bears scored 4 goals
statuscvo [17]

Answer:

The number of additional shots on goal to score 3 more goals is 36

Step-by-step explanation:

Let

x ----> the number of goals scored

y ---> the number of shots on goal

we know that

\frac{x}{y}=\frac{4}{48} ----> equation A

so

For x=3

substitute the value of x and solve for y

\frac{3}{y}=\frac{4}{48}

y=\frac{48}{4}(3)

y=36

therefore

The number of additional shots on goal to score 3 more goals is 36
