I always had trouble doing percents, but my last algebra teacher taught me an easy way, where you turn the percent into a decimal.
Maria: to find 25% of 26.50, you multiply 26.50 by 0.25 to get 6.625. now, you subtract 6.625 from 26.50 to get 19.875. which would round to 19.88$. To find the 10% sales tax, you multiply 19.88 by 0.10 or 0.1 to get 1.988. that would round to 2.00. She would then add 19.88 and 2.00 to get 21.88$.
Edwin: I am not even sure how to figure out Edwin's math, his is not even comprehendible for me.
When I'm shopping, I always use Maria's method to figure out the price of things, therefore, I am 99% sure she is correct and Edwin is not. If it said that they both came with 23$, and the price of the book is now only 21.88, then yes, they have enough money to purchase the book.
and sorry this took long, I'm multitasking.
The set that is more variable is the daily temperature as they won't be clustered but rather spread out.
<h3>How to know the set that's more variable?</h3>
The mean of the temperature will be:
= (51 + 37 + 53 + 27 + 91 + 50 + 50 + 83 + 83 + 90)/10
= 615/10
= 61.5
The mean of the precipitation will be:
= (4.5 + 3.8 + 1.4 + 2.4 + 2.8 + 4.6 + 4.7 + 2.3 + 1.5)/10
= 28/10
= 2.8
