Answer
$n = 42.5$
Work Step by Step
To solve a proportion, we use the cross products property, multiplying the numerator of one ratio with the denominator of the other ratio, and vice versa:
$17(20) = 8n$
Multiply on the left side of the equation:
$340 = 8n$
Divide each side of the equation by $8$ to solve for $n$:
$n = 42.5$
