Gregory plans to purchase a video game player. he has $500 in his savings account and plans to save $20 per week from his allowance until he has enough money to buy the player.
he needs to figure out how long it will take. what type of function should he use to model this problem? justify your answer mathematically.

25 weeks

Step-by-step explanation:

500 / 20 = 25

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

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
