Just substitute in the values in 32>7x+4
if x=-1 ---->32>7(-1)+4---->32>3 which is true.It is a solution
if x=5--->32>7(5)+4--->32>39 which is false.it is NOT a soultion
if x=0---->32>4---->which is true .It is a solution
if x=4---->32>7(4)+4---->which is true. it is a solution
There are two expressions
Price of video games: 4(25) = $100
Sale tax: 0.06(100) = $6

Step-by-step explanation:
The number of 30- period until the value if the give card be equal is 20 30- day period
<h3>How to write and solve equation</h3>
let
- Number of 30- day period = x
Card 1:
50 - 2x
Card 2:
40 - 1.50x
50 - 2x = 40 - 1.50x
50 - 40 = -1.50x + 2x
10 = 0.50x
- divide both sides by 0.50
x = 10/0.50
x = 20
In conclusion, it will take 20 30- day period until the value of the given card can be equal.
