Its $800 because to find interest u can use the formula I=PRT p is principal which is 500 times r which is rate-15/100(=15%) times 4
so the interest is 500×15/100×4=300
then u add 300 to 500 because the interest adds more money to the loan
Answer:
Step-by-step explanation:
Are the volumes equal? No, so throw out the first and the last one.
Is the volume of the pyramid greater than the volume of prism?
No, so throw out the third one
so by inspection it must be the remaining one
or mathematically
vol pyramid = (1/3)(base)(height)
vol prism = (base)(height)
vol pyramid / vol prism
(1/3)(base)(height) / (base)(height) = 1/3
Answer,
-5, 50/20, 2.43, 6

Answer:
1 haircut = 47 dollars
1 colouring = 98 dollars
Step-by-step explanation:
Let 
be equal to the cost of 1 haircut.
Let 
be equal to the cost of 1 colouring treatment.
<u>1) Form equations</u>
Equation 1: 3 haircuts + 1 colour = 239 dollars
⇒ 
Equation 2: 2 haircuts + 1 colour = 192 dollars
⇒ 
<u>2) Solve the system of equations</u>
Subtract equation 2 from equation 1 to cancel out y (elimination)
- 
⇒ 
Therefore, Natalie charges 47 dollars for 1 haircut.
Plug x back into one of the equations to solve for y
Subtract both sides by 94
Therefore, Natalie charges 98 dollars for 1 colouring treatment.
I hope this helps!
