Question

Suppose price decreases from $27.00 to 513.00. Using the mid-point formula, the percentage change in price is:_________ a) 0.7 - 70 percent b) 14 percent c) -0.7 - 70 percent. d) -0.35 -- 35 percent.

Answer 1

Answer: c) -0.7 - 70 percent.

Step-by-step explanation:

Using the midpoint formula, the change will be;

`= (P_(2) - P_(1) )/((P_(2) + P_(1))/(2) ) \\\\= (13 - 27 )/((13 + 27)/(2) )\\\\= -0.7`

= -70%
