SUBS

Let x represent number of hours after noon.

We have been given that Sara starts at noon and walks at a speed of 4 miles per hour. So distance covered by Sara in x hours would be .

We are also told that Eddie leaves the  same place an hour later. This means that Sara will be 4 miles ahead of Eddie as Sara will travel 4 miles in 1 hour.

As Eddie walks in the same direction at a speed of 5  miles per hour. So distance covered by Eddie in x hours would be .

Total distance covered by Sara when Eddie will start would be .

Now we will equate distance covered by both in x hours as:

Let us solve for x.

Since x represents number of hours after noon, so 4 represents 4 hours after noon.

Therefore, Eddie will catch up with Sara at 4:00 pm and option D is the correct choice.

Answer

Find out the how much money can be saved by buying a $1,000 television in New Hampshire .

To proof

As given

If Massachusetts has a sales tax of 6 percent and New Hampshire has no sales tax.

The cost of the telivision in New Hampshire = $1000

First find out the cost of telivision in  Massachusetts

6% is written in the decimal form

= 0.06

6% sales tax on the cost of television = 0.06 × 1000

                                                              = $60

Total price of the television in  Massachusetts = 1000 +60

                                                                          = $1060

Money saved = Television price in Massachusetts - Television price in New Hampshire

= 1060 - 1000

= $60

Therefore  $60 be the money saved  by buying  television in New Hampshire .

Option (C) is correct .

Hence proved
