A boat is marked up 20% on the oringinal price. The oringinal price was $50. What is the new price?
Answers
10% is $5.
20% would be $10 because it is double the price of 10%.
Therefore if you meant it is 20% more than the original it would be $60.
If you meant it would be 20% less is would be $40.
Sorry its not much help but i wanted to do the best i could.
20% of 100 is 20, and 50 is half of 100. that means that 20% of 100 is double 20% of 50. Since 20% of 100 is 20, and 20% of 50 is half that, 20% of 50 is 1/2 of 20, which is 10. So 20% of $50 is $10

Answer: 12 bracelets
Step-by-step explanation:
I am assuming you meant to write “Brianna has four pink bracelets, 1/3 of all her bracelets are pink. How many bracelets does Brianna have?”
If that’s what you mean to write proceed on my writing.
Write out what you know
4 pink bracelets= 1/3 of her bracelets
Equation:
4+4+4=12 bracelets
1/3+1/3+1/3=3/3=100% of her collection

a. Write and solve an equation to find the number of square yards of carpeting for which the total cost charged by the two companies will be the same.
b. Mr. Shu wants to hire one of the two carpet companies to install carpeting in his basement. Is he more likely to hire Country Carpets or City Carpets? Explain your reasoning.
Answers
22x + 100 = 25x + 70
Now lets solve step-by-step.
Apply the inverse operation 22x + 100 = 25x + 70
-22x -22x
25x - 22x = 3x
3x + 70 = 100
-70 - 70 We subtract 70 from both sides because (inverse operation)
3x = 30
3x/3 = 30/3
x = 30/3
x= 10
B) We need to find which one is the most cheap.
Lets pick an integer to replace x.
22x + 100 = 25x + 70
Lets choose '2'
22(2) + 100 = 25(2) + 70
44 + 100
50 + 70
144
120
The first one : Country Carpets charges $144 , while at the same rate, City carpets charges 120.
So, obviously, City Carpets is cheaper than that other one, so he would most likely choose that one.
Let x be the number of square yards of carpeting for which the total cost charged by the two companies will be the same.
We have an expression for the total cost of Country Carpets:
($22/ 1 yd^2)* (x yd^2) + $100
= $22*x+ $100
or 22x+ 100
We also have another expression for the total cost of City Carpets:
($25/ 1 yd^2)* (x yd^2)+ $70
= $25*x+ $70
or 25x+ 70
Now set the two expressions to be equal:
22x+ 100= 25x+ 70
⇒ 100- 70= 25x -22x
⇒ 30= 3x
⇒ 30/3= x
⇒ 10= x
The final answer for a is 10 square yards of carpeting~
b.
Let's assume that Mr. Shu wants to install carpeting for 1 square yard.
Country Carpets: $22*1+ $100= $122
City Carpets: $25*1+ $70= $95
Therefore, Mr. Shu will be likely to choose City Carpets if he wants to install carpeting for 1 square yard.
Now let's try x=11 (square yard):
Country Carpets= $22*11+ $100= $342
City Carpets= $25*11+ $70= $345
Therefore, Mr. Shu will be likely to choose Country Carpets if he wants to install carpeting for 11 square yard.
If you paid really close attention, you would notice that the price of City Carpets will be cheaper than the other when x is >0 and <10. At x=10, the price is equal. When x is >10, the price of Country Carpets will be cheaper than the other one.
So it depends:
If x were >0 and <10, Mr. Shu would be likely to choose City Carpets.
If x were 10, Mr. Shu could choose either Country Carpets or City Carpets.
If x were > 10, Mr. Shu would be likely to choose Country Carpets.
Hope this helps~
