1、What is the least positive integer that is not a factor of 25! and is not a prime number?

A 26

B 28

C 36

D 56

E 58

这个题，你看25!里面包括了2到25的所有factor了，所以你看26=2*13,28=2*14,36=2*18,56=7*8，而只有58=2*29,29不在里面，所以就选这个了

2、The fabric needed to make 3 curtains sells for $8.00 per yard and can be purchased only by the full yard. If the length of fabric required for each curtain is 1.6 yards and all of the fabric is purchased as a single length, what is the total cost of the fabric that needs to be purchased for the 3 curtains? A$40.00

B $38.40 C$24.00

D $16.00 E$12.80

Since 1.6 yards of fabric are required for each curtain, it follows that (3)(1.6), or 4.8, yards of fabric are required to make the 3 curtains. The fabric can be purchased only by the full yard, so 5 yards of fabric would need to be purchased.

Since the fabric sells for $8.00 per yard, the total cost of the fabric is$40.00. The correct answer is Choice A.

还是用汉语解释下吧，一共三个窗帘，每个1.6m，那么一共要4.8m，由于不能零卖，只能整数的卖，所以买5m，一共是5*8=40了。
