a store had sales of $480.7 billion in 2016 and $539.6 billion in 2018. use the midpoint formula to estimate the sales (in billions of dollars) in 2017. assume that the sales followed a\n$______ billion
Answer
Explanation:
Step1: Identify the mid - point formula
The mid - point formula for two values (a) and (b) is (\frac{a + b}{2}). Here, (a = 488.7) (sales in 2016) and (b=529.6) (sales in 2018).
Step2: Calculate the estimated sales in 2017
Substitute (a = 488.7) and (b = 529.6) into the formula: (\frac{488.7+529.6}{2}=\frac{1018.3}{2}=509.15).
Answer:
509.15
