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(1)/(2)* x=(7)/(2)* x=(7x)/(2)`

The weight of will be,

`(7x)/(2)=(7*22.15)/(2)=(155.05)/(2)=77.525\text{pounds}`

Hence, it weighs 77.525pounds
