When a piggy bank has 160 total coins valuing 10.50. Think about a system of equations that can be used to represent the number of nickels and dimes and then think through?

If n is the number of nickels and d the number of dimes, then the equations are:n + d = 160 (total number of coins)
5n + 10d = 1050 (total value).
And I have thought through to the answer.

Two ways that show you understand the importance of valuing each children as an individual?
It is very important to recognize that every child is an individual. Doing so enhances their perception of self worth, which in turns fosters their development into responsible and mature adults. Additionally, every child reacts to different stimuli in different ways. As a caregiver, it is important to recognize that what works for one child will not necessarily work for another, and attempting to force a method on a child often results in more harm than good.
Why do people tend to place a greater value on their money than their time when making banking choices?
For several reasons: Valuing time is very difficult. To compare two banks you would need to compile information on the amount of time each bank would take for the various processes that you are likely to use (banks are not likely to volunteer that information), how often you are likely to use these over a typical period, the consequent costs and benefits. You then need to work out the expected overall cost or benefit. If you value your time, all that is usually not worth it. On the other hand finding out about banking charges (if any) and interest rates is easy. Most people do not place much value on their time because it is too abstract. The only exception is when the car in front of them does not start moving within a nanosecond of the lights changing! And if that happens, every millisecond of delay is more valuable that the driver's sanity!
