Explanation:
According to our assumption, the toy microscope should cost less, because the children are going to just play with it. They should just get a model of microscope, but the expectation is we need not want the same work experience by using the toy microscope.
But the toy microscope is available with good magnification. So the price is equivalent to the real microscope which is available in the college.
But a factor to be noted is that, the toy microscope has low resolution, so it produce only poor quality of images.
