7 % of cost price is 2.80 , What about 1%?
7 = 2.80
1 = x (where x is the price value of 1% in dollars)
We simplify the above equation, so:
7 × x = 2.8 × 1 → 7x = 2.8 → x = 2.8 / 7 → x = 0.4 dollars
We know that 100% represents the whole price,
so if 1% is 0.4 dollars, then 100% will be 0.4 × 100 = 40 dollars
Therefore the store charged $40 dollars for the helmet before tax

Answer:
square foot per hour
Step-by-step explanation:
The total area covered = 34 square foot
Time taken = 12 hours
This implies that it takes 12 hours to cover 34 square foot.
Using proportionality,
12 hours ---------------------------------------> 34 square foot
Dividing both sides by 12
---------------------------> 
1 hour --------------------------------------->
square foot per hour
The unit rate in square feet per hour is
square foot per hour
Answer:
0.219 or 21.028%
Step-by-step explanation:
0.18 are defective, so
P(x=1) = 0.18
P(x=2) = 0.18^2 = 0.0324
P(x=3) = 0.18^3 = 0.005832
P(x=4) = 0.18^4 = 0.00104976
Then add them together: 0.21928176
