Answer:
0.50 %
Step-by-step explanation:
= profit/cost x 100%
= 11.95 - 7.95 = 4
= 4/7.95 x 100 %
= 0.50 %
Subtract to find the amount of the discount:
80.00 - 60.00 = 20.00
Divide the amount of discount by original price:
20.00 / 80.00 = 0.25
Multiply by 100 to get percent:
0.25 x 100 = 25%
Answer: 25%
Answer:
Step-by-step explanation:
p=8 cm
one side=8/4=2 cm
edge of black square=2/4=1/2 cm=0.5 cm
area of one square=(0.5)²=0.25 cm²
total area of two black squares=2×0.25=0.5 cm²
length of white rectangle=2/2=1 cm
width=2/4=1/2 cm=0.5 cm
area of one rectangle=1×0.5=0.5 cm²
area of two rectangles=2×0.5=1 cm²
total area=0.5+1=1.5 cm ²
