Given: The amount saved for trip = $75

The decided amount to save per week = $65

Let 'w' denotes the numb er of week.

Since, you need at least $635 to go on a trip to Washington, DC.

then we have the following inequality:

Hence, the inequality shows the number of weeks, w, you need to save to be able to go on the trip is

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
