Question

2. Seiji and Gavin both worked hard over the summer. Together they earned a total of $425. Gavin earned $25 more than Seiji.
(a) Write a system of equations for the situation. Use s for the amount Seiji earned and g for the amount Gavin earned.
(b) Graph the equations in the system.
(c) Use your graph to estimate how much each person earned.
Can someone give me the answer for (B) please don't put random letters

Answer 1

 a) Let G = Gavin 
Let S = Seiji 
G+S = 425 
b) G = S+25 
S+S+25 = 425 
2S + 25 = 425 
2S = 400 
G = 200 
Seiji earned 200 dollars. 
Gavin earned 200+25 dollars. ----- Gavin earned 225 dollars. 

Answer 2

The amount that Seiji earns is $200 and the amount that Gavin earns is $225 and this can be determined by forming the linear equation.

Given :

• Seiji and Gavin both worked hard over the summer.
• Together they earned a total of $425.
• Gavin earned $25 more than Seiji.

a) Let the amount that Seiji earns be 's' and the amount that Gavin earns be 'g'.

The linear equation that represents the total amount they earn is:

s + g = 425   --- (1)

The linear equation that represents the situation "Gavin earned $25 more than Seiji" is:

g = s + 25  --- (2)

b) The graph of both the equation is attached below.

c) Substitute the value of 'g' in equation (1).

s + s + 25 = 425

2s = 400

s = $200

Substitute the value of 's' in equation (2).

g = 200 + 25

g = $225
