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.

25% of what number is 75

goldenfox [79]

Let's form an equation. To find the percent of a number, you multiply the percent divided by 100 and the initial number. X will be the initial number.
.25x=75; let's divide.
75÷0.25= 300
The initial number is 300. We can make sure 75 is a quarter of 300 by dividing 300 by 4.
300÷4=75

So, the number is 300.
