Answer: Michelle visited 24 more lighthouses in Maryland than in Virginia.
Step-by-step explanation:
Based on the information given in the exercise, you know that Michelle visited a total of 30 lighthhouses.
You can express the percent in decimal form by dividing it by 100. Then:
[tex]20\%=\frac{20\%}{100}=0.2[/tex]
Let be "V" the number of lighthouses Michelle visited in Virginia. Since it is the 20% of the 30 lighthouses, this is:
[tex]V=(30)(0.2)\\\\V=6[/tex]
Let be "M" the number of lighthouses Michelle visited in Maryland ([tex]M[/tex]). This is:
[tex]M=30-V\\\\M=30-6\\\\M=24[/tex]
Therefore, you can determine that Michelle visited 24 more lighthouses in Maryland than in Virginia.
