Roland receives $500 as a graduation present from his aunt. He plans to use part of the money to purchase a laptop for $289, including tax. He will purchase some new video games with the remaining money. Each video game costs $52, including tax. Which inequality describes, v, the number of video games Roland can purchase with his graduation money?

52x < $211

Step-by-step explanation:

If Roland uses $289 to purchase the laptop from the $500 that was given to him then he would be left with

500 - 289 = $211

With this he can purchase video games. Since each video game costs the same price of $52 then we can use the variable x to represent the number of games he can buy with the following inequality...

52x < $211

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

1.0
