Answer: original price= $8
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 8 × 20/100
Discount = 8 x 0.2
You save = $1.60
Final Price = Original Price - Discount
Final Price = 8 - 1.6
Final Price = $6.40
Answer:
If the third side is x, then
The perimeter is 5+19+x.
But every side must be less than the sum of the other
two sides, so x < 5+19
x < 24
Adding 5+19 to both sides to make the left side
equal to the perimeter
perimeter = x+5+19 < 24+5+19 = 48
So 48 is the smallest whole number that is larger than the
perimeter of any triangle with a side length of 5 and a side
length of 19.

Answer:
13 chairs in each row
Step-by-step explanation:
divide 65 by 5 to get 13
To find the price per unit, divide the total price by the number of units.
2.12/25=0.08
5.09/72=0.07
Brand B is the better buy. It is cheaper per unit.
2/3 works here because its value is greater than 1/2 but less than 4/5. An easy way to visualize this is to take the decimal value of each number as decimals are often easier to understand than fractions.
1/2=.50
2/3=.67
4/5=.80
This inequality could be rewritten as .50 < .67 < .80 and would have the same value.
