I remember that the square of 12 is 144.
Let's work up from there to the squares that 180 lies between.
Keep in mind that squares are when a number multiplies by itself.
For example;
10^2 means 10 • 10, which makes the product of 100.
12^2 = 144
13^2 = 169
14^2 = 196
Well, we have 169 and 196, which 180 lies between.
Your answers are:
13 and 14.
I hope this helps!
To find the better buy we have to find the cost per pen for each.
1. 20 pens for $1.60 -> 1.60/20 = .08 cents per pen.
25 pens for $2.25 -> 2.25/25 = .09 cents per pen.
The best buy is 20 pens for $1.60 because it's cheaper per pen.
2. 13 berries for $2.60 -> 2.60/13 = .20 cents per berry
17 berries for $3.06 -> 3.06/17 = .18 cents per berry
The best buy is 17 berries for $3.06 because it's cheaper per berry.
The answer is B because when you divide the negative the sign changes :)
