With three boys on a large scale, it read 170 pounds. when adam stepped off, the scale read 100 pounds. when both adam and ben stepped off, the scale read 60 pounds. what is the weight of each boy?

Adam = 70 pounds

Ben = 40 pounds

C = 60 pounds

Step-by-step explanation:

We can work out some equations based on the given information:

We can call the boys A, B and C

so,

- Eq(1)

- Eq(2)

So we already knew the weight of boy C. (it was in the question all along)

pounds

Now to find the individual weights of the remaining boys, we can work our way backwards

we can put this value back in Eq(2), to find the weight of boy B.

the

the weight of boy B (Ben) is pounds

now we can put all of the known weights of the boys in Eq(1) to find the weight of Boy A.

the weight of boy A (Adam) is pounds

The

Adam = 70 pounds

Ben = 40 pounds

C = 60 pounds

answer: 12   they all have at least 28 days
