Sammy wants to buy a new video game that cost 41.95 he is saving 2.25 everyday. how many days did it take for him to save enough money for the video game

19 days

Step-by-step explanation:

The first day he saves 2.25.

The second day he has saved 2.25 + 2.25 or 2.25(2).

The third day he has saved 2.25 + 2.25 + 2.25 or 2.25(3)

This continues for x number of days so 2.25x.

If the video game costs 41.95 then set equal to 2.25x and solve.

2.25x = 41.95

x = 18.64

This rounds to 19.

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
