8.99 / 6 = 1.498 rounds to 1.50 per roll

the better deal (cheapest) is the 2 roll package

The length,AB of the rectangular lot is 1 foot less than two times its width, BC. If the perimeter of the rectangular lot 394 fe

r-ruslan [8.4K]

Answer:

$AB=131\ ft$

Step-by-step explanation:

we know that

The perimeter of the rectangular lot is

$P=2(AB+BC)$ ----> equation A

where

AB is the length

BC is the width

we have

$AB=2BC-1$ ---> equation B

$P=394\ ft$ ----> equation C

substitute equation B and equation C in equation A

$394=2(2BC-1+BC)$

solve for BC

$394=2(3BC-1)$

$394=6BC-2$

$6BC=396$

$BC=66\ ft$

Find the value of AB

$AB=2BC-1$

$AB=2(66)-1$

$AB=131\ ft$

Mica bought a new smart phone for $258.13. That was the price after his 18.25% discount. What was the original price of the phon

julia-pushkina [17]

The original price of phone is $ 315.76

Solution:

Given that Mica bought a new smart phone for $ 258.13.

That was the price after his 18.25% discount

To find: original price of phone

From given question,

price after discount = $ 258.13

discount = 18.25 %

Let "x" be the original price of phone

price after discount = original price - discount

$258.13 = x - 18.25 \% \text{ of } x$

$258.13 = x - \frac{18.25}{100}x$

$258.13 = x(1 - \frac{18.25}{100})$

$258.13 = x(1 - 0.1825)\\\\258.13 = x( 0.8175)\\\\x = \frac{258.13}{0.8175}\\\\x = 315.76$

Thus original price of phone is $ 315.76
