At a state fair, there is a game where you throw a ball at a pyramid of cans. if you knock over all of the cans, you win a prize. the cost is 3 throws for $1, but if have you an armband, you get 6 throws for $1. the armband costs $10.

i. write two cost equations for the game in terms of the number of throws purchased, one without an armband and one with.

Step-by-step explanation:

Let x be the number of throws and y be the cost

Without armband case

The cost for 3 throws is $1

The cost for 1 throws is

The cost for x throws is

So, is the equation for the game in terms of the number of throws purchased without an armband

With armband case

The cost for 6 throws is $1

The cost for 1 throws is

The cost for x throws is

Cost of Arm band is $10

So, Total cost for x throws with arm band =

So, is the equation for the game in terms of the number of throws purchased with an armband

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
