If Phil gets a commission of 25% on all sales and he sold $1500.00 worth goods, then he can determine the amount of his payback in following way:
$1500.00 -- 100%
$x -- 25%.
Mathematically, this is proportion:
\(\dfrac{\$1500}{\$x}=\dfrac{100\%}{25\%},\\ \\\$x=\dfrac{\$1500\cdot 25\%}{100\%}=\$15\cdot 25=\$375=\$375.00.\)
Answer: correct choice is B
