Answer:
About 714 tractors were sold in 2008
Step-by-step explanation:
Increase of 106% means:
106% in decimal is [tex]\frac{106}{100}=1.06[/tex]
Thus the increase is 1.06 of 347 which is 1.06*347=367.82
Total would be 347 + the increase = 347 + 367.82 = 714.82
Fractional tractors isn't possible so we round down, so about 714 tractors were sold in 2008
