Question

15. If p pencils cost 2D dollars, how many
pencils can be bought for c cents?​

Answer 1

Step-by-step explanation:

Start by converting c cents into dollars.

That would be c/100

p pencils cost 2D dollars.

1 pencil costs 2D/p

So 1 pencil costs 2D/p

So for c cents you can buy.

`((c)/(100) )/((2D)/(p) ) = (c)/(100) * (p)/(2D)\text{pencils}`
