Jean bought a $1,980 snow thrower on the installment plan. The installment agreement included a 10% down payment and 18 monthly
Effectus [21]

<u>Solution-</u>

The price of the snow thrower = $1980

He must pay a 10% down-payment and the rest at a $116 monthly payment for 18 months.

<u>A. How much is the down payment</u>

Down payment amount is, 10% of $1980, i.e

=1980\times \dfrac{10}{100}=\dfrac{1980}{10}=\$198

<u>B. What is the total amount of the monthly payments</u>

A monthly payment of $116 for 18 months, i.e

=116\times 18=\$2088

<u>C. How much did Jean pay for the snow thrower on the installment plan</u>

It is the sum of down-payment and total monthly payments, i.e

=198+2088=\$2286

<u>D. What is the total finance charge</u>

It the difference between the original price and the amount paid by Jean, i.e

=2286-1980=\$306

<u> E. If Jean models her payment plan as an arithmetic sequence, give the first term a1 and the common ratio d</u>

As he paid the down-payment of $198 and then a constant monthly payment of $116, so

The first term = 198

common difference = 116

The A.P. series will be, 198, 314, 430, 546, 662,.................., 2286

A passenger train left Austin, Texas at 12:00 PM bound for Dallas, exactly 210 miles away; it traveled at a steady 50 miles per
olya-2409 [2.1K]

Answer:

  1. 3 hours
  2. 1 hour 45 minutes
  3. 300 miles

Step-by-step explanation:

1. The trains are moving toward each other at a total speed of 50 +20 = 70 miles per hour. Together, they cover the 210 mile distance in ...

  time = distance/speed

  time = 210 mi/(70 mi/h) = 3 h

The trains collide after 3 hours.

__

2. The fly is closing with the freight train at a speed of 100 +20 = 120 miles per hour. Together, the fly and the train cover the initial 210 mile distance in ...

  (210 mi)/(120 mi/h) = 7/4 h = 1 hour 45 minutes

The fly first meets the oncoming freight train after 1 h 45 min.

__

3. The fly is flying for all three hours before the trains collide, so, at 100 miles per hour, will fly 300 miles.
