Question

rosa has a goal of running a total of 150 miles this month each day she ran for 6 miles . what expression could rosa use to determine how many miles she has left to run after running for d days

Answer 1

miles left = 150 - 6d

Explanation:

To create this expression, let 150 be the total number of miles she needs to run. If she runs 6 miles every day, the expression for miles she has left is the total miles - 6* how many days she has been running. Your final expression for miles she has left should be 150 - 6d.

Hopefully this helps- let me know if you have any questions!
