The answer to your question is C.48
According to the number of cups, 564 people can be invited to the party.
Step-by-step explanation:
This is a simple question of cross multiplication
<u>DATA:</u>
<em>1. Total number of cups of yogurt is 423 cups</em>
<em>2. 1 serving =
th of a cup</em>
<em>3. Each guest gets
of a cup or 1 serving</em>
<em>4. Find out how many guests can be invited to the party,</em>
Cups : People
: 1
423 : p
<em>5. Cross multiply</em>
p = 423 x 1
3p = 423 x 4
p = 
p = 564
Therefore, according to the number of cups, 564 people can be invited to the party.

Answer:
N(x) = 40 - 2x
P(x) = -2x² + 52 x - 240
maximum profit = 13
Step-by-step explanation:
given data
feeder cost = $6
average sell = 20 per week
price = $10 each
solution
we consider here price per feeder = x
and profit per feeder id here formula = x - 6
so that here
total profit will be
P (x) = ( x - 6 ) Nx
here N(x) is number of feeders sold at price = x
so formula for N (x) is here
N(x) = 20 - 2 ( x - 10 )
N(x) = 40 - 2x
so that
P(x) = (x-6) ( 40 - 2x)
P(x) = -2x² + 52 x - 240
since here
a = -2
b = 52
c = -240
a < 0
so quadratic function have maximum value of c -
so it will be
maximum value = -240 -
maximum value = 98
so here maximum profit attained at
x = 
x = 
x = 13
maximum profit = 13
