P = $2000, Rate, r = 6% = 0.06 per year, Time, t = 5 years.

For compound interest compounded annually:

A) Amount, A = P(1 + r)^t

A = 2000(1 + 0.06)⁵

A = 2000(1.06)⁵ ≈ 2676.45

Amount ≈ $2676.45

B) Interest = Amount - Principal

= 2676.45 - 2000 = 676.45

Interest ≈ $676.45

Here's a strong hint:

The $2,000 is what you brought to the bank and left there, all those years ago.
Everything over that is what it earned by being there ... the "interest".

Answer:

$E = 30 \times H$

$570

Step-by-step explanation:

Given that:

For each hour of tutoring, Lena earns 30 dollars.

E is her earning and

H is the number of hours for which she tutors.

To find:

Equation relating E to H.

Solution:

Let Lena tutors for 1 hour, then the earning = 30 dollars

Let Lena tutors for 2 hours, then the earning = 30+30 OR 2 $\times$ 30 = 60 dollars

Let Lena tutors for 3 hours, then the earning = 30+30 +30 OR 3 $\times$ 30 = 90 dollars

If Lena tutors for H number of hours, then the earning, E = 30 + 30 + .... + 30 (H times) i.e.

$E = 30 \times H$

So, the equation that relates E to H is given as:

$E = 30 \times H$

Now, it is given that she tutors for 19 hours.

Let us put H = 19 hours in the above equation:

$E = 30 \times 19 \\\Rightarrow E = \$570$

Therefore, the earning for 19 hours of tutoring is <em>570 Dollars.</em>

(y=179x<br> (y=105x+2046<br> Solve using elimination method and graph plss <br> Helpppp

elixir [45]

Answer:

$x= \frac{2046}{74}\\\\y = \frac{366234}{74}$

Step-by-step explanation:

$y = 179x\ ----- ( 1 ) \\\\y= 105x + 2046 \ ----- (2)\\\\$

$(1) => y - 179x = 0 \ ----- ( 3)\\\\(2) => y - 105x = 2046 \ ------ ( 4)$

$( 3 ) - ( 4) =>\\\\(-179x +105x ) = 0 - 2046\\\\-74x = -2046\\\\x = \frac{2046}{74}$

$Substitute \ x \ in ( 1 )\\\\y = 179x \\\\y = 179 \times \frac{2046}{74} = \frac{366234}{74}$
