CSC V2 Chapter 22 习题

Caculate the amount of CESG the federal government will contrubute this year to the RESP of a 6-year old child in a family earning income of $40,000 and contributing $2,500 to the child’s RESP.
A. $200
B. $400
C. $500
D. 600
答案是D,解释说20% on the $2,500 from the basic CESG and an additional 20% of the first $500 invested in the program($2500 x 20% + $500 x 20% = $600)
 
疑问：题目说这个家庭只放了$2500进RESP，根据政府规定就直接补贴20%就完了，不明白为什么解释说还有额外20% of the first $500。难道政府是只要放了$500就补贴20%，然后放到$2500的时候再补贴20%吗？
