First, solve for the difference between the two prices. That is, $2.79 - $2.86 which is equal to -$0.07. Divide this value by the original price and multiply by 100%. This is shown below,
                         (-$0.07 / $2.86) x100% = -2.448%
Thus, the percentage decrease is approximately equal to 2.4%.

Will the standard form 3.2 × 10–4 be more or less than 1? Explain what effect the negative exponent has. Thanks! =)
laila [671]
3.2 * 10^-4 = 0.00032
So the number is less than 1.

The effect the negative exponent has is.....well...here's an example

if the exponent was a positive it would be 3.2 *10^4 = 32,000

If it was positive you would move the decimal point to the right (for this equation) 4 times... if it was negative you would move it the other way.

-1/2 + 2/3= <br> Give simplified answer
babunello [35]
You need a common denominator of 6 because it's the least common denominator of 2 and 3. So you can change -1/2 to -3/6. And change 2/3 to 4/6. The new equation would be -3/6 + 4/6 = 1/6.
