n → smaller

20 - n → larger

4 (20 - n) = 5n - 1

80 - 4n = 5n - 1

81 = 9n

n = 9

20 - n = 11

Therefore, the numbers are 9 and 11.

Your larger number is 11 and your smaller one is 9. You solve this by first dividing 20 in half. Then you make one larger than the other by subtracting 1 from one 10 and adding adding that subtracted 1 to the other 10. Then you multiply 11 by 4 (11×4) and get 44 then multiply 9 by 5 (9×5) and get 45. Then subtract 44 from 45 (45-44) and the difference is 1.

Make a down payment of $1500 and finance the rest of $20000 at 1.9% interest rate, making equal monthly payments for 5 years.
REY [17]
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>
