Question

36.If p pencils cost c cents , how many pencils can be bought for d dollars ? A. Dp/cB. 100C /dp C. 100cd/P D. 100dp/c

Answer 1

Given:

p pencils cost c cents

so, the cost of one pencil = c/p

We will find how many pencils can be bought for d dollars

First, convert from dollars to cent

d dollars = 100d cents:

Using the ratio and proportions:

Pencil : Cents

p c

? 100d

so, the number of pencils =

`(100d\cdot p)/(c)=(100dp)/(c)`

So, the answer will be option D. 100dp/c
