What is the answer to A basket with 12 apples has a mass of 3,105 grams. The same basket with 7 apples has a jhaad of 1980 grand each apple has the same mad what is the mess of the baskets?

Please proofread, correct, and repost.

total mass = 12a + b = 3105

7a + b = 1980

5a = 1125
a = 225

b = 1980-7(225) = 405

To find the mass of the baskets, we need to determine the mass of each apple first.

Given that a basket with 12 apples has a mass of 3,105 grams, we can divide the total mass by the number of apples:
3,105 grams ÷ 12 apples = 258.75 grams per apple.

Now, let's find the mass of the basket when it contains 7 apples. Since each apple has a mass of 258.75 grams, we can multiply the number of apples by the mass of one apple:
7 apples × 258.75 grams = 1,811.25 grams.

Therefore, the mass of the basket when it contains 7 apples is 1,811.25 grams.
