the balance y {in dollars} of your savings account after t years is represented by the function y=200(1.1)^t. the begging balance of your friends account is $250,and the balance increased by $20 each year.(a)compare the balance by calculating and interpreting the average rates of change from t=2 and t=7. (b) predict which account will have a greater balance after 10 years

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
