We must find the difference between prices. $2.65 - $2.50 = $0.15. Now we need to calculate what percent $0.15 is of $2.65. It is 5.7%! The price decreased, so it is a 5.7% decrease!

Answer:

Step-by-step explanation:

1. Percent means out of 100

8% = 8/100

W = 48% *180

W = .48 *180

W =86.4

3. Is means equals and of means multiply

80 = 125% * W

80 = 1.25 W

Divide each side by 1.25

If remove the zero from 0.76 would it change the value of the number

wariber [46]

Question 1:

<h3>Answer: The number does <u>not</u> change</h3>

Removing the zero from 0.76 leads to .76 which is the same as before. Both lead to $7.6 \times 10^{-1}$ in scientific notation.

Personally I prefer the zero up front to make the decimal point stand out easier. Of course it's just a preference, so its up to you to decide which you prefer.

===========================================

Question 2:

<h3>Answer: Yes the number changes</h3>

Taking the zero out of 10.25 leads to 1.25 which is definitely a different number (and smaller). Therefore, this zero is a significant digit compared to before.
