const2013 [10]

4300 is your principal

1.8% interest rate (change it into decimal form; 0.018)

2 years is our time

We'll now multiply our variables.

4300 x 0.018 x 2 = 154.80

This shows that in 2 years at their interest rate that they have earned 154.80.

We will add the $154.80 to the original borrowed amount of 4300.

$4454.80 will be how much they will owe after 2 years.

To find out the amount in 15 months we'll divide 15 months by 12 and we get 1.25 and now we multiply the numbers again.

4300 x 0.018 x 1.25 = 96.75

They will pay $96.75 in interest within 15 months and we'll add it to the 4300.

$4397 will be how much they will pay after 15 months.

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>
