packhorses travelled along a network of bridle paths. a merchant would be away from home most of the year, carrying his takings in cash in his saddlebag. later a series of chapmen would work for the merchant, taking wares to wholesalers and clients in other towns, and with them would go sample books. before 1720,... | [

] | C | $2.50 x 1.13 = 2.83 for one skein (rounded)
$2.83 x 1.5 = $4.25 (rounded)
You could have found the basic cost of 1.5 skeins first, and then figured tax and
shipping. Your answer may be slightly different because of rounding.

regular numbers are numbers that evenly divide powers of 60 ( or, equivalently, powers of 30 ). equivalently, they are the numbers whose only prime divisors are 2, 3, and 5. as an example, 602 = 3600 = 48 Γ 75, so as divisors of a power of 60 both 48 and 75 are regular. these numbers arise in several areas of mat... | [

Explanation:
78= 2*3*13 now multiples of 78, 156 ....780, now 1000-780 = 220 only two more muktiples of 78 can exists. So total number of 3 digit Multiples of 78 are 9+2=11
91= 13*7--Total number of three digit multiples --9
No remember we have a common multiples as well-- 13*7*6=91*6=546
So tota... |
