How to interpret the circle graph?

From the circle graph, the proportion (p) of red oak is calculated as follows:

$p = 100\% - 12.5\% - 10\% - 37.5\% - 25\%$

Evaluate the differences

$p = 15\%$

Given that the total pieces of wood (n) in the workshop is 120, the number of woods that are red oak is calculated using:

$Red = p \times n$

So, we have:

$Red = 15\% \times 120$

Express 15% as decimal

$Red = 0.15 \times 120$

Evaluate the product

$Red = 18$

Hence, there are 18 pieces of red oak in Kevin's workshop
