Compare it to 1/2 (which is the same as 6/12)
Answer:
the value of her medium shirts is $60 if Ella makes 100 more shirts her new value is $600
967.50 = 450 + 28.75p
967.50 - 450 = 28.75p
517.5 = 28.75p
18 = p
The domain is {-8}
The range is {5,6,7,8}
The relation is not a function as the domain value -8 maps to multiple values. All domain values in a relation needs to map to exactly one range value for it be a function.
