Kim bought a total of $2.95 worth of postage stamps in four denominations. If she bought an equal number of 5-cent and 25-cent stamps and twice as many 10-cent stamps as 5-cent stamps, what is the least number of 1-cent stamps she could have bought?
Select the correct option:
A) 5  B) 10  C) 15  D) 20  E) 45
Let:   # of 5 and 25 cents stamps = n   # of 10 cent stamps = 2n   # of 1 cent stamps = m   Therefore:   5n + 25n + 10(2n) + m = 295 cents   50n + m = 295   Forleastnumber of 1 cents stamps, maximize 50n. Hence,   50*5 + m = 295   m = 45 i.e. 45 stamps 1 cents each   Answer: 45
