Please help me. Noah, I manages a buffet at a local restaurant. He charges 10 dollars for the buffet. On average, 16 cuffs customers choose the buff at as their meal every hour. After servings have real customers, no has determined that for every one dollar increase in the cost of the buffet that average number of customers who select the buffet will decrease by 2 per hour. The restaurant owner wants the buffet to maintain a minimum revenue of 130 dollars per hour. Noah wants to model the situation with an any quality and use the model to help him make the best pricing decision. Right, 2 expressions for the situation, one representing the cost per customer is in the other representing the average number of customers. Assumed that x represents the number of one dollar increase in the cost of the buffet. Enter the correct answer in the box type the cost expression on the first line in the customer expression on the second line.

step-by-step explanation:

b and c

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
