Answer 1

The answer is A you’re welcome

Answer 2

The linear model of her monthly earnings is; Y =1200 +0.03*X. The amount earned is 1350; choice A

Explanation:

Let Y denote her monthly earnings and X her total sales. The linear model can thus be formulated as; Y =1200 +0.03*X. We are then to find the value of Y given X =5000. We simply substitute X =5000 into the linear model which yields; Y =1350
