Question

At a cost of s stickers for c cents, how many stickers can be bought for d dollars

Answer 1

First, we need to express the amount of dollars d as cents, we can do this as we know that one dollar equals 100 cents, then d in cents would be:

`d(\text{cents)}=d*100cents`

And from the statement of the question, we know that s stickers cost c cents, we can express that cost per sticker like this:

`\frac{s\text{ stickers}}{c\text{ cents}}`

And if we want to find the amount of stickers that we can buy, we just have to multiply d in cents by the cost per sticker, like this:

`\text{number of sticker we can buy}=(s* d*100)/(c)`
