Maria invested $2,000 in an account that earns 4.5% interest compounded annually the formula for compounded interest isA(t)=P(1+
ankoles [38]
In the formula, P is the initial amount, i is the rate, and t is the time that has passed.  Simply plug in the values you know:

A(5) = 2000(1 + .045)^5 \\  \\ A(5) = 2000(1 .045)^5 \\  \\ A(5) = 2492.36387531 \\  \\ A(5) \approx 2492.36

Rounded to the nearest cent, Maria had $2492.36 in her account after 5 years (D).

A post office always charges a flat one-time fee for any order. One
docker41 [41]

Answer:

x = the flat fee = $1.5

y = fee per each letter sent = $0.7

Step-by-step explanation:

Let

x = the flat fee

y = fee per each letter sent

The equations

x + 35y = 26 (1)

x + 18y = 14.10 (2)

Subtract (2) from (1) to eliminate x

35y - 18y = 26 - 14.10

17y = 11.9

y = 11.9/17

y = 0.7

Substitute y = 0.7 into (1)

x + 35y = 26 (1)

x + 35(0.7) = 26

x + 24.5 = 26

x = 26 - 24.5

x = 1.5

x = the flat fee = $1.5

y = fee per each letter sent = $0.7
