<u>Answer:</u>
The system of equations are
x + y = 2600 …….equation (1)
and, 6x + 5y = 13700 ……equation (2)
<u>Explanation:</u>
Let x = amount of sales of phone;
y = amount of sales of computer
For phone, 6% of sales is 6% of x, or 6% * x = 0.06x.
Similarly for computer,
5% of y = 0.05y
Given the total sales; x + y = 2600
And commission; 0.06x + 0.05y = 137; or 6x + 5y = 13700
Therefore the system of equations are
x + y = 2600 …….equation (1)
6 x + 5 y = 13700 ……equation (2)
I think it is -10 i hope this helps
If 0.3 = 1 then 0.9 = 3 because 0.3+0.3+0.3=the 3.
The answer is A(jsjsjjsusudidjdidj)
Finding the perimetre: 7x+4x-3+x=12x-3
Good luck!
