so ur sis is getting more erasers that in a sense cost less

Your sister

Step-by-step explanation:

To determine those with better deal we will have to do some calculations

So let's start

You bought the 3 erasers for$1.00

So we will have to determine the amount you bought 1

3 erasers=$1.0

1 eraser=x

Cross multiply

3x=1

X=1/3

X=0.33333

Your sister bought 4 erasers for $1.25

So 1 eraser=x

Cross multiply

4x=1.25

X=1.25/4

X=0.3125

So we will have to compare the two prices and we will discover that your sister gets the better deal
