Answer
x = 17.64
Work Step by Step
$\frac{250}{24.8} = \frac{x}{1.75}$
$24.8x = (250)(1.75)$
$24.8x = 437.5$
$\frac{24.8x}{24.8} = \frac{437.5}{24.8}$
x = 17.64
Check answer
$(250)(1.75) = (24.8)(17.64)$
437.50 = 437.47
Since the value of x was rounded, the cross products are not exactly equal but are close enough to indicate the answer is correct.
