Answer:
2%
Step-by-step explanation:
Let x be the first number
It increases by 70 %
The new number is
m = x+ .70x
= 1.7x
Let y be the second number
It decreases by 40 %
The new number is
n =y - .40 y
= .6y
The product of the original numbers is xy
The product of the new number is
mn = (1.7x * .6y) = 1.02xy
The new number is larger than the old number so it is an increase.
Percent increase is new - original divided by original times 100%
Percent increase = (1.02 xy - xy)
----------------- * 100%
xy
= .02 xy
------- * 100 %
xy
= .02 * 100 %
= 2%

Step-by-step explanation:
The number is ...
0.0000024 = 2.4×0.000001 = 24×0.0000001
The first of these equivalents can be written as ...
2.4×10^-6 . . . . matches no answer choice (correct answer)
The second of these can be written as ...
24×10^-7 . . . . matches choice (a)
__
Usually "scientific notation" requires there be one digit left of the decimal point in the mantissa. As we have noted above, no offered answer choice matches this form. The only choice that is equivalent to the given number is the one shown above.
