Question

On a recent shopping trip, Arnold started with $150. He spent these amounts at various stores: $49.81, $32.43, $25.90, $14.58, $23.33. How much remained of $150 when he was finished? Estimate by rounding amounts to the nearest dollar, then computing.
	A.	-$3
	B.	$4
	C.	$5
	D.	$6

anonymous · Answer

you start by rounding the amounts so:

50 + 32 + 26 + 15 + 23 = 146

then you substract that from the $150, so:

$150 - $146 = $4
