The best way to solve this problem is with a simple equation: part = percent (in decimal form) x whole
In this problem, we're trying to solve for the whole amount that the camera can hold, so we'll assign that the variable w.
We can use the information they gave us - 96 is the part, and 24% is the percent. We'll convert that to decimal form - 0.24
Then, we just plug these values back into the above equation:
96 = 0.24w
Divide both sides by 0.24 to get w on it's own, and you have your answer!
400 = w
Therefore, the memory card can hold up to 400 pictures.
Note: this equation is super helpful. It's good to have on hand for any problem involving percents, because you can solve for the part, percent, or whole depending on the problem.
