You and your sister go to the store. You buy 3 erasers for a $1.00 . Your sister buys 4 erasers for $1.25 . Explain who gets the better deal .

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

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.
