The graphs show the amounts of medicine in two patients after receiving injections. The circles show the medicine in patient A and the triangles show that in patient B.
One equation that gives the amount of medicine in milligrams, m, in patient A, h hours after an injection, is m=300(\frac{1}{2})^{h}.
What could be an equation for the amount of medicine in patient B?

m=200(\frac{7}{10})^{h}

m=200(\frac{3}{10})^{h}

m=500(\frac{3}{10})^{h}

m=500(\frac{7}{10})^{h}
