Then just 35% of food budget spent on restaurant meals in 1990,and was approximately half of that spent on home cooking。In 2000，the proportion of food budget spent on restaurant meals was the same as that spent on home cooking，was account for 50% respectively。 In conclusion（or overall），people have a tendency to eat at restaurants and spend more and more money on restaurant meals。 Please help me correct my mistakes if you find。Thanks in advance。
