A clothing company sells slacks that are either blue or gray and pleated or non-pleated. Last month, the company sold 5 times as

qwelly [4]

Answer:

138 pairs

Step-by-step explanation:

The number of blue pleated slacks is 5 times the number of gray pleated slacks, so:

$blue\ pleated = 5 * gray\ pleated$ (eq1)

The number of gray non-pleated is twice the number of blue non-pleated slacks, so:

$blue\ nonpleated = 2 * gray\ nonpleated$ (eq2)

The total number of blue slacks is 333, and the total number of gray slacks is 225, so we have that:

$blue\ pleated + blue\ nonpleated = 333$ (eq3)

$gray\ pleated + gray\ nonpleated = 225$ (eq4)

If we add (eq1) and (eq2), we have:

$blue\ pleated + blue\ nonpleated = 5*gray\ pleated + 2*gray\ nonpleated$ (eq5)

Using (eq3) and (eq4) in (eq5), we have:

$333 = 2*225 + 3*gray\ pleated$

$gray\ pleated = 117/3 = 39$

From (eq1), we have:

$blue\ pleated = 5*39 = 195$

From (eq3), we have:

$blue\ nonpleated = 333 - 195 = 138$

Which expression represents the value of the series below?<br> 3+ 7 + 11 + 15 + ... + 1,671

torisob [31]

Answer:

Step-by-step explanation:

This is an Arithmetic Series with common difference 4 and first term 3

so the nth term an = 3 + (n -1)4

= 4n - 1.

The sum of n terms

= n/2 (a1 + L)

= n/2(3 + 1671)

= 837n.

There are (1671-3) / 4 + 1 = 418 terms in the series,

so the total value of the series is 837*418

= 349,866.
