Step-by-step explanation:
We have to find the reported happiness of person of family income of $25,000, $35,000 and $45,000
Given that the formula for finding relation between a people happiness and his income is
y = 0.065x - 0.613
a) find the happiness of person of family income os $25,000
we put x = 25 as in the equation above
Hence, person happiness with with family income of $25,000 on a scale of 3 is y = 1
That means they come under catergory "not to happy"
b) Find the happiness of person of family income os $35,000
we put x = 35 as in the equation above
Hence, person happiness with with family income of $35,000 on a scale of 3 is y = 1.7
That means they come under catergory "not to happy" and "fairly happy"
c) Find the happiness of person of family income os $45,000
we put x = 45 as in the equation above
Hence, person happiness with with family income of $45,000 on a scale of 3 is y = 2.3
That means they come under catergory "fairly happy"
Answer:
The salespeople earn for the sale of a suit = $13.
The salespeople earn for the sale of a pair of shoes = $8.
Step-by-step explanation:
Let x be the commission for each suit and y be commission for each pair of shoes.
We have been given that for selling 3 suits and one pair of shoes, Carla has earned $47 in commission. We can represent this information as:
We are also told that for selling 7 suits and 2 pairs of shoes, Benicio has earned $107 in commission. We can represent this information as:
We will use substitution method to solve our system of linear equations. From equation (1) we will get,
Substituting this value in equation (2) we will get,
Upon combining like terms we will get,
Therefore, the salespeople earn $13 for the sale of a suit.
Let us substitute x=13 in equation (1).
Therefore, the salespeople earn $8 for the sale of a pair of shoes.
