First, we define variables:
x: small hat
y: medium hat
z: large hat
We now write the system of equations:
x + y + z = 47
5.50x + 6y + 7z = 302
-3x + y = 0
We can write the system in matrix form as:
Ax = b
Where,
A = [1 1 1; 5.50 6 7; -3 1 0]
b = [47; 302; 0]
x = [x; y ; z]
Solving the system we have:
x = 6
y = 18
z = 23
Answer:
the coach did purchase 23 large hats

Answer:
<u>The cost per gallon is US$ 1.87</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Number of gallons of gas = 13
Cost of the gallons of gas = US$ 24.31
2. What is the cost per gallon?
Cost per gallon = Cost of the gallons of gas/Number of gallons of gas
Replacing with the real values, we have:
Cost per gallon = 24.31/13
Cost per gallon = 1.87
<u>The cost per gallon is US$ 1.87</u>
<h3>The answer of your question. I also have given some reasons of it. Hope it will help you. </h3>
You're in high school and can't do this, wow that's sad since i'm in seventh grade. Anyway you divide 2 from $47.00 to get $23.50 and 3 divided by $47.00 to get $15.66 repeated. round to get $15.67 or $15.70.
