An equivalent expression would be s+15
You simplify the expression.
So yea the answer is s+15
The principal amount is 
<u>SOLUTION:
</u>
Given that, simple interest
;
after 3 years
We have to find the principal.
Now, let the principal amount be p.
Then,
Now, we know that, Balance = Principal amount + Simple Interest

Answer:
The dimensions of the can that will minimize the cost are a Radius of 3.17cm and a Height of 12.67cm.
Step-by-step explanation:
Volume of the Cylinder=400 cm³
Volume of a Cylinder=πr²h
Therefore: πr²h=400

Total Surface Area of a Cylinder=2πr²+2πrh
Cost of the materials for the Top and Bottom=0.06 cents per square centimeter
Cost of the materials for the sides=0.03 cents per square centimeter
Cost of the Cylinder=0.06(2πr²)+0.03(2πrh)
C=0.12πr²+0.06πrh
Recall: 
Therefore:



The minimum cost occurs when the derivative of the Cost =0.






r=3.17 cm
Recall that:


h=12.67cm
The dimensions of the can that will minimize the cost are a Radius of 3.17cm and a Height of 12.67cm.
Answer:
:)
Step-by-step explanation:
15x=300
x will equal 20
20x=300
x will equal 15
