Answer:
Markup 90%
Step-by-step explanation:
If $40 is 100% of the price
then
$76 is ..........x
Cross multiplication
40(x) = 76(100)
40x = 7600
Divide by 100
x = 190
190% = 100% + 90%
That means that the price is the whole price(100%) plus 90%
so the markup is 90%
ANOTHER WAY:
The difference in prices is $76-$40=$36. So, we need to find what percentage of 40 is 36.
We do this by dividing: 36/40=0.9, which is 90%. So, the markup is 90%.

diagonal = 9√2 ≈ 12.73
the diagonal splits the square into 2 right triangles with the hypotenuse being the diagonal of the square
using Pythagoras' identity
d = √(9² + 9²) = √162 = 9√2 ≈ 12.73 ( to 2 dec. places )
