Answer:
50 years old
Step-by-step explanation:
The BC/AD time line is like a number line: the negative side of 0, the numbers move backwards; and the positive side of 0 moves normally. If you have -25, then move to +25, you have just moved 50 places.
Hope this helps :)
The price of the bushel is 1.22, 1.41, 1.38, and 1.27.
To calculate the weighted average, all you need to is to just add all the values given above and then divide it by 4, since we only have 4 values of the bushel.
So: 1.22 + 1.41 + 1.38 + 1.27 = 5.28
5.28 / 4 = 1.32
Round it off to only two significant figures, you would get: $1.30.
