Question

If one case of conductor ties weighs 22.15 pounds, how much will 3½ cases of ties weigh?

Answer 1

Let x represent one case of conductor ties

If one case of conductor ties weighs 22.15 pounds, i.e

$x=22.15\text{pounds}$

For 3 1/2 cases of ties i.e

$3\frac{1}{2}\times x=\frac{7}{2}\times x=\frac{7x}{2}$

The weight of will be,

$\frac{7x}{2}=\frac{7\times22.15}{2}=\frac{155.05}{2}=77.525\text{pounds}$

Hence, it weighs 77.525pounds
