Let's solve your inequality step-by-step.
−7n + 6 ≥ − 43

Step 1: Subtract 6 from both sides.
−7n + 6 − 6 ≥ −43 − 6 − 7n ≥ −49

Step 2: Divide both sides by -7.
−7n − 7 ≥ −49 − 7n ≤ 7

So, true

$\sf{ \dfrac{12}{-4} = -3}$

$\sf{ \dfrac{-36}{12} = -3}$

You are purchasing soft drinks for the company annual party. You expect about 32 people to be there. You want to allow at least

qaws [65]

32*18=576 oz. 

Store A offers 24-12 oz cans for $5.89. That means $5.89 gets you 288 oz. Store B offers 12-12oz cans for $3.79, so that means $3.79 gets you 144oz. 

Store A is $5.89 per every 288 oz. You need 576 oz, which is double that. That means it will cost you twice as much as it would buying 24-12 oz cans: 
$5.89*2=$11.78 

Store B is $3.79 for 144 oz. As previously stated, you need 576 oz, so you'll need to buy 4 12-packs of 12 oz cans: 
$3.79*4=15.16 

So not only is Store A a better deal, but they'll save you $15.16-$11.78=$3.38 dollars.
