------------------------------
Equations:
Quantity Eq.::: x + y = 480
Value Eq.::::: 5x +8y = 2895
------
Multiply thru the Quantity equation by 5
5x + 5y = 5*480
5x + 8y = 2895
---
Subtract the 1st from the 2nd:
3y = 495
y = 165 (# of non-student tickets sold)
---
Since x+y = 480, x = 480-165 = 315 (# of student tickets sold)

Answer:

1) as-16a

taknig a as common

=a(s-16)

2)as-4a³

taking a as common

=a(s-4a²)

3)2a³+8a-4a²-16

taking common terms

=2a(a²+4)-4(a²+4)

=(2a-4)(a²+4)

again taking common

=2(a-2)(a²+4)

A suit costs $95. Barry has a discount coupon for 10% off and the city has a 4.5% sales tax. What is the final cost of the suit?

seropon [69]

So first you need to do the discount

(95)(0.9) = 85.5

then add the 4.5% sales tax:

(85.5)(1.045) = $89.35
