The correct answer is:  [C]:  " $4290.00 " .
_______________________________________
Explanation:
_________________________________________
Given:  principal, "P":  equals:  $14,300  ;
                 rate, "r" : equals:  7.5 %  = 7.5 / 100 = 0.075 ; 
                time, "t" (in years): equals:  4  ;
_________________________________________
What is the interest, "i" ? 
_________________________________________
  Note:  The formula:  i = P * r * t   .
_________________________________________
So, we plug in our given values for "P", "r", and "t", and solve for "i" (interest).
__________________________
i = ($14,300) *(0.075) * (4)  ;

i = $1,490 ;  which is answer choice:  [C]:  " $4290.00 " .

Noah manages a buffet at a local restaurant. He charges $10 for the buffet. On average, 16 customers choose the buffet as their
kicyunya [14]

Answer:

$3 max

Step-by-step explanation:

Charge= b, Customer= c, Revenue= r

r= bc, currently, r= 16*10= $160

We know that: b+1 ⇒ c-2  and the target is r ≥ 130

So, this will all be reflected as:

b=10+x ⇒ c= 16-2x

  • (10+x)(16-2x) ≥ 130
  • 160 -20x +16x - 2x² ≥ 130
  • -2x² - 4x + 30 ≥ 0
  • x² + 2x -15 ≤ 0
  • (x+1)² ≤ 4²
  • x+1 ≤ 4 (negative value not considered)
  • x ≤ 3

As we see the max increase amount is $3, when the revenue will be:

(10+3)*(16-3*2)= 13*10= $130
