You can either do;

1. 90(2) = 100(2)

180 = 200

In 3 minutes, they can write 200 words. So now we can divide by 3.

3/3 = 1 minute

200/3 ≈ 66.666

or

2. 90/3 = 30 secs

100/3 ≈ 33.333

30(2) = 1 minute

33.333(2) ≈ 66.666

Either way, the admin assistant can write 67 words per minute. (Rounded to the nearest whole)

Marizza181 [45]

Answer:

Originally, you will <em>pay</em> $95.75 for the dog.

Step-by-step explanation:

Given:

Maintenance cost of dog after 55 months = $5,468.50

Maintenance cost of dog after 82 months = $8,053.75

To Find:

How much did you pay for the dog originally = ?

Solution:

It is stated that the maintenance cost is same from month to month

Now 82 - 55 = 27 months

For 27 we have paid

$8,053.75 - $5,468.50

$2585.25

But one month the amount paid will be

$\frac{2585.25}{27}$
