Answer: 15,000
Explanation:
replace "is" with = (equal sign)
replace "of" with × (multiplication sign)
and divide 0.3% by 100 (move decimal 2 places to the left) to convert it from a percent to a decimal. --> 0.3% = 0.003
Then solve the equation!
Let n represent the unknown number, then
![45=0.003n\\\\\\(45)/(0.003)=(0.003n)/(0.003)\\\\\\\large\boxed{15,000}=n](https://img.qammunity.org/2020/formulas/mathematics/college/uvx0eaceetgrnrlx3bzkzrt7msusnerhsf.png)
