In every aspect of life, we are applying equations to solve for a particular variable. From figuring out dosages of medicine to building a book shelf or garden, equations can be applied to eliminate trial, and error. In solving equations, measurements are needed to calculate a solution. For example, in construction, measurements of dimensions are used to determine the amount of supplies necessary. Another example is time to travel from point A to point B; measurements needed to determine the time would be the distance and the speed the vehicle travels. Using an example from construction or traveling please explain how equations will be helpful. Thank you!
