Andrea multiplied 6.75 x 10^6 and 0.2 x 10^6 and got 6.95 x 10^6.
Question asked:
Explain Andrea’s mistake and give the correct answer.
Solution:
The above question is of <u>exponential question</u>:
Here Andrea simply <u>added </u>6.75 to 0.2 and got 6.95 and took 10^6 as common and written down wholly 6.95 x 10^6 which is incorrect.
Here we <u>multiply</u> 6.75 to 0.2 and get 1.35 and secondly to multiply 10^6 with 10^6 we have to understand the rule of exponents:-
<u>As we know:</u>
<u></u>

Hence when we multiplied 6.75 x 10^6 and 0.2 x 10^6 originally we got

Step-by-step explanation:
amount increased to the toy = y
new price of the toy after adding markup = z
y= ( ( 25/100) × X )
therefore z= x+y
D. v = 15.00n
Since there each n is worth 15.00, we multiply n by 15.00 to find the total value, v.
