Answer: Maria has 10 bills of 5€ and 10 bills of 10€.
She has a total of 150€.
Step-by-step explanation:
Let be "f" the number of 5€ bills that Maria has and "t" the number of 10€ bills that Maria has.
Set up a system of equations:
Use the Substitution method to solve the system of equations:
1. Solve for "f" from the first equation:
2. Substitute the equation obtained into the second equation and solve for "t".
Then:
3. Substitute the value of "t" into the equation and evaluate:
Therefore, Maria has 10 bills of 5€ and 10 bills of 10 €.
So the total amount of money she has, is:
She has a total of 150€.
Answer: 5 * 23 = 115 so 40<
Step-by-step explanation:
Answer:
Addition and subtraction are inverse operations. Start with 7, then add 3 we get 10, now subtract 3 and we get back to 7.
Another Example: Multiplication and division are inverse operations. Start with 6, multiply by 2 we get 12, now divide by 2 and we get back to 6.
Answer:
The rectangular prism with these dimensions w = 3 cm, l = 5 cm, h = 5 cm has the largest volume.
Step-by-step explanation:
The formula for the Volume of a V = 3 * 5 * 5
V = l * w * h
V = 3 * 5 * 5
V = 75 cm³
The rectangular prism with these dimensions w = 3 cm, l = 5 cm, h = 5 cm has the largest volume.
The total amount Sam will pay in all will be $2,400,000
<h3>Simple interest </h3>
From the question, we are to determine the interest Sam pays in all
Using the simple interest formula,
I = PRT
From the given information,
P = $2,000,000
R = 5% = 0.05
T = 4
Putting the parameters into the formula,
I = $2000000 × 0.05 × 4
I = $400000
The interest Sam will pay is $400,000
The total amount Sam will pay in all will be $2,000,000 + $400,000
= $2,400,000
Hence, the total amount Sam will pay in all will be $2,400,000
