Answer:
The cost of a shirt is $16 and the cost of a sweater is $33
Step-by-step explanation:
Let
x -----> the cost of a shirt
y -----> the cost of a sweater
we know that
-----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
The solution is the point (16,33)
see the attached figure
therefore
The cost of a shirt is $16 and the cost of a sweater is $33
20x + 45y = 9500 is the linear equation for given scenario
<em><u>Solution:</u></em>
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
<em><u>From the above statement, we can frame a equation as:</u></em>
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
Thus the linear equation for given scenario is found
