Final answer:
Marley has ridden a total of 41 miles this week, by adding her distances from each day: 6 miles on Monday, 7 miles on Tuesday, and 28 miles on Wednesday.
Step-by-step explanation:
The question asks us to calculate the total number of miles Marley has ridden on her bike over three days. On Monday, Marley rode 6 miles, on Tuesday she rode 7 miles, and on Wednesday she rode 4 times farther than she did on Tuesday.
To find out how far Marley rode on Wednesday, we multiply Tuesday's distance by 4:
- 7 miles (Tuesday) × 4 = 28 miles (Wednesday)
Now, we add up the miles from all three days:
- 6 miles (Monday) + 7 miles (Tuesday) + 28 miles (Wednesday) = 41 miles
Therefore, the answer is Marley has ridden 41 miles so far this week. However, this option is not provided in the multiple-choice answers, indicating perhaps a typo in the question or the response options.
