Question

The gym has 4 times as many baseballs than basketballs the gym has 25 total balls how many more baseballs than basket balls does the gym have

Answer 1

Let $b$ be the number of baseball and $k$ be the number of basket ball.

We have the following system:

$\begin{cases}b=4k\\b+k=25\end{cases}$

Substitute the first equation into the second:

$4k+k=25 \iff 5k=25 \iff k=5$

which yields

$b=4k=4\cdot 5 = 20$

So, there are 20 baseballs and 5 basketballs, meaning that there are 15 more baseballs than basketballs.
