Note: to round to the nearest ten, look to the first place digit. if it is 5 or greater, round up, if 4 and lower, round down

<em>124 rounded to the nearest ten = 120</em>
<em>38 rounded to the nearest ten = 40</em>
<em>71 rounded to the nearest ten = 70</em>
<em>207 rounded to the nearest ten = 210

120 + 40 + 70 + 210 = 120 + 110 + 210 =  230 + 210 = 440

440, or C </em>is your answer
