The plot below shows the volume of paint left in 444 cans.
1 answer:
The amount of paint that would be contained in each of the can would be 8.
<h3>How to solve for the amount of paint.</h3>
Using the information in the question we have the following
We have to solve the equation as
(2 1/2) + 2(4) + 1(5 1/2) =
2.5 + 8 + 5.5
= 16
Each of these would have to hold 16/2 = 8 pints.

Answer:
Step-by-step explanation:
The formula of simple interest is:
Where I is the interest earned after t years
r is the interest rate
is the initial amount
We know that the investment was $20,000 in two accounts
_______________________________________________
<u><em>For the first account</em></u> r = 0.07 per year.
Then the formula is:
Where
is the initial amount in account 1 at a rate
during t = 1 year
<u><em>For the second account </em></u>r = 0.05 per year.
Then the formula is:
Where
is the initial amount in account 2 at a rate
during t = 1 year
Then
We know that the final profit was I $1,280.
So
Substituting the values ,
and I we have:
As the total amount that was invested was $20,000 then
Then we multiply the second equation by -0.07 and add it to the first equation:
Then
