Al, Bob, Cal, and Ed all bought items fromthe mail-order magazine. Al and Bob paid $150,Bob and Cal paid $200, Cal and Dot paid $170, Dot and Ed paid $210 and Ed and Al paid $100. How much did each person pay?

Al: $125, Bob: $175, Cal: $185, Ed: $155, Dot: $105

Step-by-step explanation:

Al and Bob: 150 divided by 2 = 75

Bob and Cal: 200 divided by 2 = 100

Cal and Dot: 170 divided by 2 = 85

Dot and Ed: 210 divided by 2 = 105

Ed and Al: 100 divided by 2 = 50

Al: $75 + $50 = $125, Bob: $75 + $100 = $175, Cal: $100 + $85 = $185,

Ed: $105 + $50 = $155, Dot: $105
