Let the cost of a green pill be x. Thus the cost of a pink pill is x+1.
Emma has to take one green pill and one pink pill each day for two weeks.
Number of green pills required is 14. Number of pink pills required is 14.
By Problem , Cost of 14 Green pills + Cost of 14 Pink pills = 546
14x + 14(x + 1) = 546
Thus , x = 19
So , Cost of one GREEN PILL is 19$. Cost of one PINK PILL is 19 + 1 = 20$.
