Since 3 neckties will be out from the
store, so you need to know how much is the cost of 3 ties.
$59.99 x 3 = $179.97 and divide it by two
because the costumer will only pay for 2
$179.97 / 2 = $89.99 is the new price
Mark up = 89.99 – 59.99 = $30.00
% mark up = [(89.99/59.99) -1] * 100
= 50%

Adding a negative is the same as subtracting a positive,
So,
5 + (-7.5) = 5 - 7.5
which is equal to,
-2.5
You can also graph this on a number line
Answer:
4/10
Step-by-step explanation:
Louise's family traveled 3/10 of the distance to her grandmother's house on Saturday.
Let us represent total distance = 1
The remaining distance left is calculated as:
1 - 3/10
Lowest common denominator = 10
= 10 - 3/10 = 7/10
They traveled 4/7 of the remaining distance on Sunday.
This is calculated as:
= 4/7 × 7/10
= 4/10
What fraction of the total distance to her grandmother's house was traveled on Sunday?
A. m^2 - 36 = 0
m^2 = 36
m = √36 = 6 or -6
b. 3x^2 + 15 = 0
3x^2 = -15
x^2 = -5
x = √(-5) not possible unless complex numbers is applied
-1 = i^2
x = √(-5) = √(5i^2) = √5i
c. 4d^2 + 16 = 16
4d^2 = 0
d^2 = 0
d = 0
Hope it helped!
Answer:
-16
Step-by-step explanation:
-a/3 >5,,,, a/3 < - 5,,,,,, a< - 15 hence a should be - 16
