4.) This spring has been.a dry season in Miami, Florida, and the river is at a much lower level than it typically is. During the first week in April, Harry measured the river to be - 2 inches (2 – inches below its normal level). When he measured the river's level again in the last week in April, he found it to be -1 - inches. How much higher was the river after Harry measured it in the last week of 2 April?
