Question

Determine whether the cost for ordering multiple items that will be delivered is sometimes, always, or never proportional

Answer 1

Determine whether the cost for ordering multiple items that will be delivered is sometimes, always, or never proportional.
It is always proportional since the cost for ordering multiple items adds weight and the cost increases per parcel. Proportionality is relating to its relationship mainly positive since as the weight increases the cost also escalates in the process.
