Jennifer has 4/5 as many pictures on her camera has luisa does. jennifer has 28 pictureson her camera. how many pictures do jennifer and luisa have in all?
a.63
b.60
c.70
d.35

Let us assume the number of pictures that Luisa has = x
Number of pictures Jennifer has in her camera = 4x/5
It is also given in the question that Jennifer has a total of 28 pictures in her camera.
Then we can write the equation as
4x/5 = 28
4x = 28 * 5
4x = 140
x = 140/4
  = 35
So the number of pictures that Luisa has = 28
Number of pictures that Jennifer and Luisa have in all is = 28 + 35
                                                                                          = 63
So the correct option among all the options given in the question is option "a".
