Answer:
Larger number = 32
Step-by-step explanation:
Smaller number = x
Larger number = y
y - x = 8 -----------(I)
3y = 4x ---------------(II)
3y/4 = x
Plug in x = 3y/4 in equation (I)
![y - \frac{3}{4}y = 8\\\\\frac{4}{4}y - \frac{3}{4}y = 8\\\\\frac{1}{4}y = 8\\](https://tex.z-dn.net/?f=y%20-%20%5Cfrac%7B3%7D%7B4%7Dy%20%3D%208%5C%5C%5C%5C%5Cfrac%7B4%7D%7B4%7Dy%20-%20%5Cfrac%7B3%7D%7B4%7Dy%20%3D%208%5C%5C%5C%5C%5Cfrac%7B1%7D%7B4%7Dy%20%3D%208%5C%5C)
y = 8*4
y = 32
Plug in y = 32 in equation (II)
3y = 4x
3*32 = 4x
4x = 3*32
x = ![\frac{3*32}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%2A32%7D%7B4%7D)
x = 3 *8
x = 24
Answer:
3(3x+2)

Answer:
The price of each CD before tax is $15.70
Step-by-step explanation:
Given that:
Number of CDs bought by Reuben = 5
Cost of five CDs = $81.50
Sales tax on each CD = $0.60
Sales tax on 5 CDs = 0.60*5 = $3.00
Price of CDs without tax = 81.50 - 3.00 = $78.50
Price of each CD = ![\frac{Cost\ of\ CDs}{No.\ of\ CDs}](https://tex.z-dn.net/?f=%5Cfrac%7BCost%5C%20of%5C%20CDs%7D%7BNo.%5C%20of%5C%20CDs%7D)
Price of each CD = ![\frac{78.50}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B78.50%7D%7B5%7D)
Price of each CD = $15.70
Hence,
The price of each CD before sales tax is $15.70
