Answer

$840

Work Step by Step

When you round to the nearest dollar, you are rounding to the nearest whole number, or the ones place. To round 840.08 to the nearest dollar, draw a "cut-off" line after the ones place: "840". Next, look at the first number you cut off: "0". If the number is 4 or below, round down to the nearest dollar: "840". Note: You are rounding to the nearest whole number, so do not show any decimal places.
