He still needs 40 oz to drink.
40 (less than or equal to sign) x
Step-by-step explanation:
*Find how many ounces in 8 cups
8 cups × 8 ounces = 64 ounces
**Figure out the sign
- it has to be equal to because his goal is to drink at least 64 oz.
- the sign has to also be greater than because he want to drink more than 64 if possible for him
***What goes on the other side of the sign?
- the 24 oz that he already drank plus the needed amount, let it be x for unknown
- the equation is 24 + unknown, or 24 + x
****Join all parts to get equation:
[tex]64 \leqslant 24 + x[/tex]
*****isolate x
- subtract 24 to both sides to cancel out the 24 on the side with x
******Answer to how many oz he still needs:
40 (less than or equal to sign) x
Oops I had said it was greater than but it's less than because the x is supposed to be equal to or greater than 40 oz.
