Lamar Wells · Answer 1

It'll take 7 days for both tanks to have the same amount of water.

Day 1

108 - 5 = 103

45 + 4 = 49

Day 2

103 - 5 = 98

49 + 4 = 53

Day 3

98 - 5 = 93

53 + 4 = 57

Day 4

93 - 5 = 88

57 + 4 = 61

Day 5

88 - 5 = 83

61 + 4 = 65

Day 6

83 - 5 = 78

65 + 4 = 69

Day 7

78 - 5 = 73

69 + 4 = 73
