In scientific notation, you need a number from 1 to less than 10 multiplied by a power of 10.
To turn 384,400 into a number from 1 to under 10, place a decimal point after the 3.
Now you have a number from 1 to less than 10.
3.844
Now count the number of places the decimal point moved left from its original position.
The decimal point was here: 384,400. after the last zero.
The decimal point moved 5 places to the left to be placed after the 3.
Since the decimal point moved 5 places left, the exponent of the 0 is 5.
384,400 = 3.844 * 10^5
Answer:
Thus last month Calvin made $414.90 from all the paintings sold at the art shows.
Step-by-step explanation:

gives as the profit for number paints sold.
We also know last month he sold six large paintings and three small paintings thus from our variables above we can say:
Eqn(1).
Thus the total profit of all paintings sold would be:
which by pluggin in Eqn(1) values gives
Thus last month Calvin made $414.90 from all the paintings sold at the art shows.
