It costs $7.75 to enter an arcade and $0.25 to play an arcade game. You have $8.25. Write an equation that represents the number g of games you can play.
An equation is = 8.25.

The equation can be written as 7.75+0.25g=8.25 and in this case g would represent 2  

Step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
