Hmm lets re-check the equation

dude:

Its supposed to be an inequality so you're supposed to have a `<, >, ≤, or ≥`

EndersWorld:

How so?

EndersWorld:

I am confused.

dude:

The question says `at least $25.50` so that means `≤25.50`

EndersWorld:

I got you.

EndersWorld:

Now what??

dude:

Lets re-write the equation The rate is .80 per day so: \(.8x≤25.50\) Now from here we can solve for x

EndersWorld:

Divide both sides by .8?

dude:

Right
