3200 dollars is placed in an account with an annual interest rate of 5.25%. To the nearest tenth of a year, how long will it take for the account value to reach 13400 dollars?

80 years

Step-by-step explanation:

3200 ÷ 100 = 32

32 × 5.25 = $168 - per year

13400 ÷ 168 = 80 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

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
