Question

according to the plot, how much weight was lost in total?
pounds lost each week
each × represents one weak
a. 8½
b. 7½
c. 9½
d. 5½

Explanation:

Step1: Calculate the total weight lost

We have \(2\) weeks of \(1\) pound lost (\(2\times1 = 2\)), \(2\) weeks of \(1\frac{1}{4}\) pounds lost (\(2\times1\frac{1}{4}=2\times\frac{5}{4}=\frac{5}{2} = 2.5\)), \(1\) week of \(1\frac{1}{2}\) pounds lost (\(1\times1\frac{1}{2}=\frac{3}{2}=1.5\)) and \(1\) week of \(2\) pounds lost (\(1\times2 = 2\)).
