You have taken unit for mass as grams.
Converted mass:-
![\\ \sf\longmapsto 2752.512g](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%202752.512g)
Hence our and should be
![\\ \sf\longmapsto 2.752kg](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%202.752kg)
Answer:
32 CDs, 13 Videos
Step-by-step explanation:
You can represent this question using variables.
Let x = #CDs sold, Let y = #videos sold.
You can formula two equations with the information given:
3x + 7y = 187
x + y = 45
Substitute x into the equation above by reducing the equation below:
x + y = 45 -> x = 45 -y
Since we are now able to remove x from the equation, plug in your new value into the equation above.
3(45-y) + 7y =187
135 - 3y +7y = 187
135 + 4y = 187
4y = 52
y = 13
Knowing the value of y, simply plug in this y value to solve for x:
x + 13 = 45
x = 32
