k0ka [10]

Let the number of cookies David has = c

Number of cookies given to Jeff = 8

So cookies left with David = c-8

David splits the cookies in half with Tod. So cookies left with David are =

$\frac{c-8}{2}$

Same number of cookies are with Tod = $\frac{c-8}{2}$

He finds the number of cookies that Tod has is 1/2 the difference of C and 8. Write an expression to represent the number of cookies that Tod has.

Hence, number of cookies with Tod are= $\frac{c-8}{2}$
