To solve the set of equations given above, we can use the substitution method where we substitute one equation to the other and solving for one variable. We do as follows:
<span>0.4x - 0.1y = 2
x = 5 + 0.25y
0.2x + 0.5y = 1
</span>0.2(5 + 0.25y)+ 0.5y = 1
y = 0
x = 5
Therefore, the correct answer from the choices is option A, (5,0).

Step-by-step explanation:
Given

(every hour)
Required
Explain why it is linear
First, we need to determine the equation that represents the scenario
Let x be the number of hours worked and y be the number of figurines at x hours.
The equation is determined as follows:

This gives:


Reorder

A linear equation is of the form

By comparison,
is equivalent to 
<em>Hence, we can conclude that the situation is linear</em>
90/12=7.5.
so.....
7.5 times 15 is 21.
That added to the orginal amount equals to : 111.
