Make a down payment of $1500 and finance the rest of $20000 at 1.9% interest rate, making equal monthly payments for 5 years.
pshichka [43]
We know that we have to m<span>ake a down payment of $1500 and finance the rest of $20000 at a 1.9% interest rate, making equal monthly payments for 5 years. Our first step to solve this problem would be to convert 5 years into months. 

1 year = 12 months 

12 * 5 = 60 months 

Therefore, in 5 years there are 60 months. 

Now lets solve this problem step by step. 

Subtract the down payment from $20,000

</span>$20000-$1500=$18500

Multiply the remaining number by the interest rate. 

$18500 *1.9 = $35150 

Divide 35150 by number of months in 5 years (60)

$35150 / 60 = $585 

<span>Therefore, you have to pay $585 per month. </span>

Ethan rollerbladed a total of 623 \text{ km}623 km623, start text, space, k, m, end text over ddd days. He rollerbladed the same
Sever21 [200]

Answer:

Ethan rollerbladed each day  \frac{623}{d}  kilometers.

Step-by-step explanation:

Given:

Ethan rollerbladed a total of 623 km over d days.

Now, to find the kilometers Ethan rollerblade each day.

Total number of distance rollerbladed = 623 km.

Total number of days = d.

<u><em>As, Ethan rollerbladed each day the same distance.</em></u>

Now, to get the distance Ethan rollerbladed in each day we divide total number of distance rollerbladed by total number of days:

Ethan\ rollerbladed\ each\ day\ =\ \frac{Total\ number\ of\ distance\ rollerbladed}{Total\ number\ of\ days}

Ethan\ rollerbladed\ each\ day\ =\ \frac{623}{d}

Therefore, Ethan rollerbladed each day \frac{623}{d}  kilometers.

Someone quickly hell
Elza [17]

Answer:

£3,780

Step-by-step explanation:

Total rows = 19 rows

Seats per row = 28 seats

Cost of tickets per seats = £8.75

Total number of seats at the concert = Total rows × seats per row

= 19 rows × 28 seats

= 532 seats

The tickets for 100 seats have not been sold

Total number of tickets = sold tickets + unsold tickets

532 = sold tickets + 100

532 - 100 = sold tickets

432 = sold tickets

Sold tickets = 432 tickets

Total cost estimate of sold tickets = sold tickets × cost of tickets per seats

= 432 × £8.75

= £3,780

Find the equation of the line which has slope of -5 and y-intercept 7. Give your answer in the form y=mx+b
zhuklara [117]

Answer:

y = - 5x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Here m = - 5 and b = 7, thus

y = - 5x + 7 ← equation of line
