Answer:
The rest of the question is the attached figure
The percent change = [tex]\frac{final-initial}{initial} *100[/tex]
If (+ve) increase and if (-ve) decrease
Part A: What is the percent of change in the cost of a pizza?
The initial price = $7.5
The final price = $9
The percent change = [tex]\frac{9-7.5}{7.5}*100 = 20[/tex]%
Part B: What is the percent of change in the cost of a cheeseburger?
The initial price = $5
The final price = $6.5
The percent change = [tex]\frac{6.5-5}{5}=30[/tex]%
Part C: What is the percent of change in the cost of a serving fries?
The initial price = $2
The final price = $4.5
The percent change = [tex]\frac{4.5-2}{2} = 125[/tex]%
Part D: What is the percent of change in the cost of a hot dog?
The initial price = $2.5
The final price = $2
The percent change = [tex]\frac{2-2.5}{2.5} = -20[/tex]%
