Jessamine wants to ride her bike at least 85 miles per week. She rides to and from school 5 days per week. Her house is 6 point 2 5 miles from her school. She rides an additional 2 point 5 miles for each trip, t , she makes around the park. Which inequality represents the situation?
Answer
A
5 2 6 point 2 5 plus 2 point 5 t is greater than 85
B
5 2 6 point 2 5 plus 2 point 5 t is less than or equal to 85
C
5 2 6 point 2 5 plus 2 point 5 t is less than 85
D
5 2 6 point 2 5 plus 2 point 5 t is greater than or equal to 85
Explanation
Riding to and from school is 2 × 6.25 = 12.5 miles each day. Over 5 days, Jessamine rides 5 × 12.5 = 62.5 miles, so her total is 62.5 + 2.5t. “At least 85 miles” means greater than or equal to 85, so the correct choice is D.
