Very easy!
6 people= 12 servings so 1 person= 2 servings
We have 112 people so we need 112 x 2= 224 servings
So she will make 224 servings with an 8 servings pan, 224/8= 28 pans.
The minimum number of pans she need in order to serve 112 people is 28 pans!
7 + 5 + 2 = 14 because seven plus five is twelve, twelve plus two is fourteen.
$500*1.03*t = $250*1.04*t , solve for t. This is the time at which the investments will yield the same amount
X + 5 = 15 I believe this is the correct answer
