For x = 4
7 x 4 + 49 = 77
Answer Is 77
<span>They should produce 100 Explorers and 275 Grande Expeditions.
To maximize revenue, we want to use all 375 frames. Since the more expensive bike take longer to make, we also want to use all 450 hours so we can make as many of the more expensive bikes as possible with the 375 frame. This helps us create a 2 variable system that can be solved.
Let x=Explorers and y=Grande Expeditions
x+y=375
2x+3y=450</span>
B. Square root of 9 (which is 3) because it is the only one that is a number that terminates. All others are non repeating.
Let the cost of a chicken be x and the cost of a duck, y, then
50x + 30y = 550 . . . (1)
44x + 36y = 532 . . . (2)
(1) x 6 ⇒ 300x + 180y = 3,300 . . . (3)
(2) x 5 ⇒ 220x + 180y = 2,660 . . . (4)
(3) - (4) ⇒ 80x = 640
⇒ x = 640 / 80 = 8
From (1): 50(8) + 30y = 550
⇒ 30y = 550 - 400 = 150
⇒ y = 150 / 30 = 5
Therefore, the price of a chicken is $8 and the price of a duck is $5.
