• C. $23<s<40$

Answer 1

The correct option is B $25\le s\le 40$

Here, Sally sold at least 25 cupcakes out of 40 cupcakes.
It is given that $s$ is the number of cupcakes sold.
$\Rightarrow s\ge 25$
There were a total of 40 cupcakes. $\Rightarrow s\le 40$
$\Rightarrow s\ge 25$ and $s\le 40$
$\Rightarrow 25\le s\le 40$
