Step-by-step explanation:
Hi there!
The answer is : 0.15p = p - 150
Here's why :
First store :
15% of p is the same thing as saying 15% times p and 15% is equal to 0.15, which explains the 0.15p
Second store:
p is reduced by 150, which explains the p - 150
Since the price of the both stores are equal, it explains why 0.15p is equal to p - 150
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
You have three card : 3, 4, 5 and 6.
You first pick one card randomly, the probability of picking a 3 is:
P = 1/4
You then pick a second card without putting the first card back, the probability of picking a 3 is:
P = 1/3
=> The probability of picking a 3 and then picking a 3:
P = (1/4) x (1/3) = 1/12
Hope this helps!

The square feet of landscaping will the two companies carry out that enables them to charge the same amount is 30
What is the total of the landscaping contract for each company?
The total cost of the landscaping contract for each of the two companies is the sum of the fixed consulting fee plus the multiple of variable charge per square foot multiplied by the number of square feet of landscaping
Company A:
Total cost=300+7S
S=square foot
Company B:
Total cost=120+13S
At the point where the square foot are the same they charge the same amount
300+7S=120+13S
300-120=13S-7S
180=6S
S=180/6
S=30 square foot
