Correct answer is Naomi calculation is incorrect and correct monthly interest rate is 2%.

Solution:

We are given that quarterly interest rate =6%

That means interest rate per quarter is 6%.

Since quarter means 3 months, interest rate per 3 months =6%

Hence interest rate per one month=6/3=2%

That means monthly interest rate is 2% which means Naomi calculation is incorrect.

3x + 4y -25 =0 represents the amount of change sianna should recieve

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
