Brainliest for correct awnser! Which variable is most important in this problem? One year, a farmer harvested 50,000 bushels of wheat on her family farm. Three years later, she harvested 12,000 more bushels of wheat from the same fields. How much wheat did she harvest that year?A. The area of the farmB. The amount of wheat harvested in the later yearC. The change in the amount of wheat harvested

C. the change in the amount of wheat harvested.

Step-by-step explanation:

Already, the question states "...how much wheat...", which implies that you must find a amount of wheat.

Also, another implication is "...12,000 more..." (emphasis added), which usually amounts to you adding (hence more) to the original amount.

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
