$132.00

Step-by-step explanation:

15 cases at $66; 66 divided by 15= $4.40 a case

20 cases at $88; 88 divided by 20=$4.40 a case

35 cases at $154.00; 154 divided by 35=$4.40 a case

therefore 30 cases x $4.40 per case = $132.00

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.
