Answer:
$130.7086
Step-by-step explanation:
List price of phone answering system = $99.86
Handset cord = $8.95
Telephone wire = 45 cent/foot ; length = 50 feet
Rebate on phone system = $5
Store coupon =$1 of each accessory
Sales tax = 6% on final price
Price before coupon = (99.86 + 8.95 + (50*0.45)) =$131. 31
Number of accessories = 3
Total coupon = $5 + ($1 * 3) = $8
Price after coupon = final price : $131.31 - $8 = $123.31
Sales tax = 0.06 * $123.31 = $7.3986
Amount paid = $123.31 + $7.3986 = $130.7086
Answer:
C.
Step-by-step explanation:
If you know how much each class is selling tickets for and how much they've already raised then you take those two values and set them equal to each other.
<em>2.5t + 350 = 3t + 225</em>
To actually find the number of tickets each class would have to sell you would just solve for t.
12/28 is equal to 3/7 (divide both the numerator and the denominator by the highest common factor).
Answer:
x² - 9
Step-by-step explanation:
(x + 3)(x - 3)
= x(x - 3) + 3(x - 3) Distributive property
= x² - 3x + 3x - 9
= x² +( -3x + 3x) - 9 Associative
= x² + 0x - 9 Addition
= x² - 9
The answer is choice A and here's why
The 2/5 outer most exponent means that we can break it down into 2*(1/5). The 2 is going to apply as an exponent for the whole parenthesis group. The 1/5 indicates we have a 5th root (similar to a square root or cube root,but instead of 2 or 3, it's 5)
In essence, I'm saying that
![\LARGE x^{m/n} = \sqrt[n]{x^m}](https://tex.z-dn.net/?f=%5CLARGE%20x%5E%7Bm%2Fn%7D%20%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D)
