The cost of single and double mucho are $5.5 and $6.5 respectively.
Let:
- cost of double mucho = d
- single mucho = d - 1
Creating the equation which represents the scenario:
16(d - 1) + 22d = 231
16d - 16 + 22d = 231
38d - 16 = 231
38d = 231 + 16
38d = 247
d = 247/38
d = 6.5
Cost of Single mucho :
d - 1
6.5 - 1
= 5.5
The cost of single and double mucho are $5.5 and $6.5 respectively.
