The amount of money, a, accrued at the end of n years when a certain amount, p , is invested at a compound annual rate, r, is given by the equation a =p(1+r)n. when joseph invests $500 in an account that pays 9% interest compounded annually, what is joe's approximate balance after 7 years? question 9 options: a) $258.38 b) $3815.00 c) $914.02 d) $932.54

  or  

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

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
