If consonants are free, determine the cost of the five vowels A, E, I, O, and U from the following clues:
Audacious costs $260 Equivocation costs $340 Inimitable costs $255 Onomatopoeia costs $435 Unambiguous costs $225
Solution:
The answer is:
a = $60
e = $75
i = $40
o = $50
u = $25
To solve it, I set up 5 simultaneous linear equations: (I used brackets to indicate each equation) 2a + i + o + 2u = 260 [1] a + e + 2i + 2o + u = 340 [2] a + e + 3i + = 255 [3] 2a + e + i + 4o = 435 [4] a + i + o + 3u = 225 [5] 3*[2] - [5]: 2a + 3e + 5i + 5o = 795 [6] -2*[2] + [1]: - 2e - 3i - 3o = -420 [7] [4] - 2*[3]: - e - 5i + 4o = -75 [8] [6] - 2*[3]: e - i + 5o = 285 [9] [8] + [9]: - 6i + 9o = 210 [10] [7] + 2*[9]: - 5i + 7o = 150 [11] 5*[10]: -30i + 45o = 1050 [12] -6*[11]: 30i - 42o = -900 [13] [12] + [13]: 3o = 150 o = 50 then substitute back to find i = 40, e = 75, a = 60, and u = 25.
