Choose the number sentence that best relates to the problem. Do not
compute. The seventh and eighth graders at Midville Middle School held a fundraiser. The seventh graders raised $526.34 and the eighth graders raised $601.87.
How much more money did the eighth graders raise than the seventh graders?

$601.87 + $526.34 =
$526.34 + $601.87 =
$526.34 – $601.87 =
$601.87 – $526.34 =
