Let $r$ $r$ equal the amount of rain.

We can then write an inequality as:

$r \geq 3$ $r >= 3$

You would use $\geq$ $ge$

You want to make sure that you use a 'greater than or equal to' inequality to match the meaning of 'at least'.

Rain $\geq$ $ge$ 3 inches

$x \geq 3$ $x>=3$

Convert the words into an inequality with $x$ $x$ being inches of rain:

$overbrace("At least")^(x>=)$ $overbrace(3 "inches")^3$

$x>=3$

Have a nice day!

$x ≥ 3$

Let $x$ represent inches of rain. Since it says "at least", we know $3$ is the smallest value it can be. This means your answer is

$x ≥ 3$

since $x$ can be $3$ but can't be any lower than that.
