Acadiana Cinema 7 charges a special admission price for adults and a lower admission price for children. The total admission price for a group of 2 seniors and 9 children is $36. The total admission price for a group of 4 seniors and 6 adults is $30. What are the admission prices a senior and an adult?

Children = 2.25 ; Adult = 3.5

Explanation:

Given that :

Admission prices :

Let :

Senior fees = x

Children fees = y

2x + 9y = 36 - - - - - (1)

4x + 6y = 30 - - - - - (2)

Multiply (1) by 2 and (2) by 1

4x + 18y = 72 - - - (3)

4x + 6y = 30 - - - (4)

Subtract 4 from 3

12y = 42

y = 42 /12

y = 3.5

Put y = 3.5 in (2)

4x + 6(3.5) = 30

4x + 21 = 30

4x = 30 - 21

4x = 9

x = 9/4

x = 2.25

Children = 2.25 ; Adult = 3.5

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.
