In order to fulfill a local school’s request for x cakes, a parents agreed to each bake an equal number of cakes. If p of the parents did not bake any cakes, which of the following represents the additional number of cakes that each of the other parents had to bake in order for the school’s request for x cakes to be fulfilled?
Answer/Solution
px/(a(a-p))
Steps/Work
No of cakes each parent has to bake : x/a
No of parents did not bake cake = p
No of cakes that were not baked by p parents = p*x/a
No of parents has to bake additional cakes = a-p
additional number of cakes that each of the other parents had to bake in order for the school’s request for x cakes = px/(a(a - p))
Answer B
No of parents did not bake cake = p
No of cakes that were not baked by p parents = p*x/a
No of parents has to bake additional cakes = a-p
additional number of cakes that each of the other parents had to bake in order for the school’s request for x cakes = px/(a(a - p))
Answer B
