Answer:

$3.50

Step-by-step explanation:

Since the total amount he spent is $29.5

He bought magazine for$15.50 and 4erasers at x

So to determine the amount he spent on erasers,it will be

29.5-15.5

14.0

So he spent $14.00 on 4 erasers so to determine the amount he spent on each eraser

It will be

4 erasers=14

1 erasers=c

Cross multiply

14=4c

Divide both sides by 4

c=3.5

So he bought each eraser for $3.50
