$\\ \sf\longmapsto \dfrac{(0.0225)^{\frac{-3}{2}}\times (0.0001)^{\frac{3}{4}}}{(0.0125)^{\frac{1}{3}}}$

$\\ \sf\longmapsto \dfrac{((0.15)^2)^{\frac{-3}{2}}\times ((0.1)^4)^{\frac{3}{4}}}{(0.5)^3)^{\frac{1}{3}}}$

$\\ \sf\longmapsto \dfrac{(0.15)^{2\times \dfrac{-3}{2}}\times (0.1)^{4\times \dfrac{3}{4}}}{(0.5)^{3\times \dfrac{1}{3}}}$

$\\ \sf\longmapsto \dfrac{(0.15)^{-3}(0.1)^3}{(0.5)^1}$

$\\ \sf\longmapsto \dfrac{\dfrac{1}{(0.15)^3}\times 0.001}{0.5}$

$\\ \sf\longmapsto \dfrac{\dfrac{1}{0.003375}(0.001)}{0.5}$

$\\ \sf\longmapsto\dfrac{ \dfrac{1000000}{3375}\times \dfrac{1}{1000}}{0.5}$

$\\ \sf\longmapsto \dfrac{\dfrac{1000}{3375}}{0.5}$

$\\ \sf\longmapsto \dfrac{1000}{3375}\times \dfrac{10}{5}$

$\\ \sf\longmapsto \dfrac{2000}{3375}$

$\\ \sf\longmapsto 0.592$

irina [24]

Answer:20%

Step-by-step explanation:so we start with x as the year before. then we get 2x from 100%. this year it would be 2x times 150% which is equal to 3x added to the year before. That would be 5x. 5x compared to x people would think is 500% but it is switched the other way to 20%.
