Answer:

the length of the entire plank is less or equal to 20 meters

Step-by-step explanation:

when the wooden plank is divided into 8 sections, the length of each section is 5/2 meters or less. Since we don't know exactly what is the length of every part, we just can calculate the maximum value of the wooden plank.

The maximum length of the entire plank is given by the next equation:

X maximum= (# sections)*(length maximum of every section)

X maximum= 8 * 5/2 meters

X maximum = 20 meters

This result says that X is less or equal to 20 meters.

Marina wants to purchase a rosebush ford dollars at a garden store. She has a coupon good for
soldier1979 [14.2K]

Answer:

Part A:  <u>0.9d - 4.5</u>

Part B:  <u>0.9d - 5</u>

Part C:  <u>Order that will save Marina money is "discount applied first, then coupon"</u>

<u></u>

Step-by-step explanation:

Part A

The rosebush costs "d" dollars

Coupon = $5 OFF

Discount = 10%

We want to find cost of rosebush when COUPON APPLIED 1st and DISCOUNT APPLIED 2nd.

Cost = d

Coupon Applied Cost = (d - 5)

Discount Applied Cost = 10% off means 100 - 10 = 90% of the price remains, that is 90/100 = 0.9 times the price, so:

0.9(d - 5) = <u>0.9d - 4.5</u>

<u></u>

Part B

When we apply 10% discount to the initial price of "d", we get 90% of the price remaining.

So, price would be:

Normal Price = d

Discount Price = 0.9d

Now, coupon applied of $5, we get:

<u>0.9d - 5</u>

<u></u>

Part C

We have two expressions, let the original price, d, be 100, so

Part A price would be 0.9d - 4.5 = 0.9(100) - 4.5 = 85.5

Part B price would be 0.9d - 5 = 0.9(100) - 5 = 85

So, Marina will save up money going on the 2nd option.

<u>Order that will save Marina money is "discount applied first, then coupon"</u>
