Answer :
We can find the mass of 5 apples by subtracting 3105 by 1980
3105-1980 = 1125g
5 apples = 1125g
1 apple = 1125g/5
1 apple = 225g
Now that we know the individual mass of each apple, we can now calculate the mass of the basket.
12 apples + 1 basket = 3105g
12(225g) + 1 basket = 3105g
2700g + 1 basket = 3105g
1 basket = 3105g - 2700g
1 basket = 405g
The mass of the basket is 405g
To check our work we can plug the values back in the equation to see if we get the right answer
12(225) + 405 = 3105
2700 + 405 = 3105
3105 = 3105
3105-1980 = 1125g
5 apples = 1125g
1 apple = 1125g/5
1 apple = 225g
Now that we know the individual mass of each apple, we can now calculate the mass of the basket.
12 apples + 1 basket = 3105g
12(225g) + 1 basket = 3105g
2700g + 1 basket = 3105g
1 basket = 3105g - 2700g
1 basket = 405g
The mass of the basket is 405g
To check our work we can plug the values back in the equation to see if we get the right answer
12(225) + 405 = 3105
2700 + 405 = 3105
3105 = 3105
