A sign at a bakery show s8 cookies for $10 and 12 cookies for $16. Find the unit price to the nearest cent (hundtreth) for each option?

Answer 1

8 cookies: 1 cookie =$1.25

12 cookies: 1 cookie =$1.33

Explanation:

The formula for price per unit is :
`(price)/(unit)`

Lets first work out the price per unit for the 8 cookies. You can do this by dividing the price of 10 by the amount of 8, this gives you $1.25. This means that the price per cookie is $1.25.

Now to work out the price per cookie for 12 cookies. You can do this by dividing the price of 16 by the amount of 12, this gives you $1.33. This means that the price per cookie for this offer is $1.33.

1) Divide 10 by 8.

`10/8=1.25`

2) Divide 16 by 12.

`16/12=1.33`
