Answer:

A

Step-by-step explanation:

You can write an expression to represent the total cost of a pair of shoes. The price of the shoes is the variable r. The shoes are marked down 20% or 0.2r. So the new price of the shoes will be r - 0.2r. You will also have to pay a tax of 5% or 0.05 of the new price. This is written as 1.05(r - 0.2r). You can simplify it by doing whats in the parenthesis.

1.05(r - 0.2r) = 1.05r(0.8r) = 0.84r

Andru [333]
Let the numbers be x and y with x being the larger number.

Given,

x - y = 5

x = 5 + y

Also given,

x = 1 + 2y

5 + y = 1 + 2y

y = 4

x = 5 + y = 9

Hence, the two numbers are 9 and 4.
