Question

The cost of the family’s cell phone plan rose from $130 to $194 when they added a phone for their daughter. What was the percent of increase?

Answer 1

Answer:

49%

Step-by-step explanation:

Step one:

initial price=$130

final price=$194

Step two:

we know that the percent increase is given as

% increase= final-initial/initial

substituting we have

% increase= 194-130/130*100

% increase= 64/130*100

% increase= 0.49*100

% increase= 0.49*100= 49%

therefore the percent increase is 49%
