Question

On Monday, stock A's price fell 0.67 and stock B's price fell 0.60. Stock C's price did not fall as much as stock A's, but it fell more than stock B's. Which answer choice shows a reasonable answer for how much stock C's price fell?
A) -0.70
B) -0.63
C) -0.56
D) -0.48

Answer 1

First lets write down what we know....

Stock A dropped 0.67, so...

StockA= -0.67

Stock B dropped 0.60, so...

StockB= -0.60

Stock C dropped more than Stock B but not as much as Stock A, so we can write the inequality:

StockB≥StockC≥StockA

Now lets fill in the values that we know...

-0.60 ≥ StockC ≥ -0.67

So we're looking for a number in between -0.60 and -0.67...

A) -0.70 is NOT between the two numbers

B) -0.63 IS between the two numbers

C) -0.56 is NOT in between the two numbers

D) -0.48 is NOT in between the two numbers

Answer= B) -0.63
