Answer:
33 3/12
Step-by-step explanation:
i’m pretty sure this is right :)
Cost=22+7*g
Cost for 3 games = 22+7*3=43
I'm guessing it's like this
example
18=2*3*3=(2¹)(3²)
315/5=63
63/3=21
21/3=7
factored form is 3*3*5*7=(3²)(5¹)(7¹)
hi
u0 = 64 with u(n+1) = un *0.75
u3 = 64 *0.75^3 = 27
sum is : 64 * ( 0.75^4 -1) / 0.75-1 = 175
manual proof : 64 + 48+36+27 = 175
