There were 60 points on tom s first math test. he scored 75% of the points. how

Multiply 60 by .75, which gives you 45 Points. The answer is B.

75%  = 0.75

so the answer is 60 * 0.75  = 45  (b)

For this case we will first look for the total cost of the purse.
 We then have the following rule of three:
 14.95 $ > 100%
 x > 105%
 Clearing x we have:
 x = (105/100) * (14.95)
 x = 15.6975 $
 The amount needed to buy the purse is:
 15.6975 - 10 = 5.6975 $
 
 holley needs 5.6975 $ to buy the purse
