Answer:

See process for finding the percent change below.

Explanation:

The formula for find the change in value over time is:

#p = (N - O)/O * 100#

Where:

#p# = percent change in value - what we are solving for
#N# = the New Value - $175 for this problem
#O# is the Old Value - $200 for this problem

Substituting the New Value and Old Value into the formula gives:

#p = (175 - 200)200 * 100#

#p = -25/200 * 100#

#p = -2500/200#

#p = -12.5#

There was a -12.5% change in the price or a 12.5% reduction.

Answer:

The percent change is #-12.5%#, which is a percent decrease.

Explanation:

The percent of change is determined by subtracting the first price from the second price, then dividing by the first price times 100.

Difference

#($175-200)=(-$25)#

Percent change

#(-$25)/($200)xx100=-12.5%#
