$\left(\dfrac{2}{5}x+\dfrac{5}{8}\right)+\left(\dfrac{1}{5}x-\dfrac{1}{4}\right)=\left(\dfrac{2}{5}x+\dfrac{1}{5}x\right)+\left(\dfrac{5}{8}-\dfrac{1}{4}\right)\\\\=\dfrac{2+1}{5}x+\left(\dfrac{5}{8}-\dfrac{1\cdot2}{4\cdot2}\right)=\dfrac{3}{5}x+\left(\dfrac{5}{8}-\dfrac{2}{8}\right)\\\\=\dfrac{3}{5}x+\dfrac{5-2}{8}=\boxed{\dfrac{3}{5}x+\dfrac{3}{8}}$

Answer:

4.25GB

Step-by-step explanation:

To get the answer, you must first turn the percentage into a decimal or a number by moving the imanginary decimal from right to left two times before adding it to the given storage of Model A.

25% = 0.25

So, the 25% now becomes 0.25 and can now be added to 4.

4 + 0.25 = 4.25

Thus, the answer will be 4.25GB. Model B has a storage of 4.25GB.
