- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define Systems</u>
x + 3y = 9
2x - 3y = 3
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: 3x = 12
- Divide 3 on both sides: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: x + 3y = 9
- Substitute in <em>x</em>: 4 + 3y = 9
- Isolate <em>y</em> term: 3y = 5
- Isolate <em>y</em>: y = 5/3
<u>Step 4: Graph Systems</u>
<em>Check the solution set.</em>
Let her initial cost be 100. Hence with 50% profit SP is 150.
Now due to additional investment, cost increases to 125 but SP remains at 150. Therefore new profit % is 25/125×100 =20% is the new Profit %.
Hence decrease in Profit % = 50- 20 = 30%.
Answer:
f(1) = 257
Step-by-step explanation:
x-variable: 1 (time is the independent variable)
y-variable: 257 (number of visitors is the dependent variable)
When the time is at 1 (1pm), there are 257 visitors
