Using the perimeter of the rectangle, it is found that she should buy at most 16 plants.
---------------------------
The perimeter of a rectangle of length l and width w is given by:
In this question, the perimeter is of 1 ft by 4.5, thus, 
, and the perimeter is:
- Perimeter of 11 ft.
- The plants will be at least 8 inches = 2/3 feet apart along the perimeter, thus:
1 plant - 2/3 ft
x plants - 11 ft
Applying cross multiplication:
At least 8 inches apart(can be more), thus she should buy at most 16 plants.

Answer:
80 pages
Step-by-step explanation:
First, work out how many minutes are in two hours.
2 hours = 120 minutes.
Multiply 2/3 by 120
2/3 × 120 = 240/3
Simplify the the fraction
240/3 = 80/1 = 80.
We can find the price per arc by dividing the total price by the amount of arc.
so in this case
5625 is the total money spent
and 4.5 is what they get when spending that amount of money
5625 / 4.5
= 1250
The price per arc is $1250
therefore, the answer is $1250.

Answer:
The merchant buys 30 shirts originally.
Step-by-step explanation:
Let us assume that the merchant bought x numbers of shirts in $120.
So, the cost for each shirt is $
.
Now, if the cost for each shirt is reduced by 1$, then he would have bought 10 shirts more i.e. (x + 10) shirts in $120.
So, we can write the following equation as
⇒(120 - x)(x + 10) = 120x
⇒ 120x - 10x + 1200 - x² = 120x
⇒ x² +10x - 1200 = 0
⇒ x² + 40x - 30x - 1200 = 0
⇒(x + 40)(x - 30) = 0
⇒ x = - 40 or x = 30
But x can not be negative.
Hence, the merchant buys 30 shirts originally. (Answer)
