Estimate: $30,000$ Exact: $28,988$

Work Step by Step

We need to subtract: $~~~75,078$ $-\underline{46,090}$ First, we estimate by rounding: $~~~80,000$ $-\underline{50,000}$ $~~~30,000$ Next, we find the exact answer: $~~~75,078$ $-\underline{46,090}$ $~~~28,988$ We see that our estimate and exact answers are fairly similar.
