Answer:

$442.1 per month

Step-by-step explanation:

Lilly took 80/20 mortgage to buy house costing $ 100000

80% × 100000 = 80000 for the first at 4.75%

80000 × 4.75% = 80000 × 0.0475 = $ 3800 as interest per year,

20% × 100000 = 20000 for the second mortgage

20000 × 7.525% = 20000 × 0.07525 = 1505 as interest per year

add the first interest and the second interest

3800 + 1505 = 5305

divide the answer by 12 months to find the monthly payment

5305 / 12 = $442.1 per month

Vera is using her phone.Its battery life is down to 2/5,and it drains another 1/9 every other. How many hours will her battery l

Margarita [4]

Let x be total hours of battery life. We have been given that battery life of Vera's phone is down to 2/5. So remaining battery life,

$1-\frac{2}{5}=\frac{5-2}{5}=\frac{3}{5}$

We have been also given that it drains another 1/9 every other hour. Now let us substitute our given information into an equation.

$\frac{1}{9}\cdot x=\frac{3}{5}$

Now we will solve for x.

$x=\frac{3\cdot 9}{5}=\frac{27}{5}$

$x=(5+\frac{2}{5})hours$

Let us convert 2/5 into minutes. We know 1 hour has 60 minutes.

$60\cdot \frac{2}{5}=24\text{minutes}$

Therefore, remaining battery life will be 5 hours and 24 minutes.
