Answer:
The company decided to increase the price by $9.60, or by 48%.
Step-by-step explanation:
To measure the price difference in dollars is simple, just subtract the old price from the new one:
[tex]29.60 - 20 = 9.60[/tex]
Divide the price change by the old price to find the price increase in percentage:
[tex]9.60 \div 20 = 0.48 \\ 0.48 \times 100\% = 48\%[/tex]
