Introductory Algebra for College Students (7th Edition)

The number we are looking for is $56$.
We need to set up the equation first for this problem. We break down the different portions of the statement and translate them algebraically: "$14$ is" means $14 =$ "25%" can be changed into a decimal, which becomes $0.25$. "Of what number" means to multiply by $x$. We can put all the parts together to set up an equation we can solve: $$14 = 0.25x$$ We divide each side by $0.25$ to solve for $x$: $$x = 56$$ The number we are looking for is $56$.
