during the second quarter of 1984, a total of 2,976,000 domestic cars were sold. if this was 24 percent greater than the number sold during the first quarter of 1984, how many were sold during the first quarter?
my answer: 2,976,000(1-0.24)
the answer in OG is 2,976,000(1+0.24)作者: himba 时间: 2004-10-17 13:45
我的思路是...假設the first quarter of 1984賣 X 量;the second quarter of 1984就是賣(1+0.24)X 量...2976000=(1+0.24)X...求觧就可得X----->即為the first quarter of 1984賣的量了ANS應該是2400000
