Total value of ratio = 4+3+1 = 8
value of 1 unit = 64/8 = 8
numbers are 4(8), 3(8), 1(8) = 32, 24, 8
so, the greatest number is 32

The easiest way to do this is to work out the lowest common multiple of 10 and 1 by listing the multiples:
12: 12,24,36,48,60,72
10: 10,20,30,40,50,60
We can then see that the lowest number of plates and cups is 60 of each.
We can then work out the costs:
Cups:
60 total = 5 packages
5 packages = $15
Plates:
60 total = 6 packages
6 packages = $30
The total cost is then $15 + $30 = $45
Answer:
x = -(-20)² ± √(-20)² - 4(16)(-6) / 2(16)
Step-by-step explanation:
Given quadratic equation:
16x² - 20x - 6 = 0
Quadratic formula is given by:
x = -b² ± √b² - 4(a)(c) / 2a
16x² - 20x - 6 = 0
From the equation,
a = 16
b = -20
c = -6
x = -b² ± √b² - 4(a)(c) / 2a
x = -(-20)² ± √(-20)² - 4(16)(-6) / 2(16)
x = -(400) ± √(400) - (-384) / 32
x = -400 ± √400 + 384 / 32
x = -400 ± √784 / 32
x = -400 ± 28 / 32
x = (-400 + 28) / 32 or x = (-400 - 28) / 32
