A set of 3 erasers costs $1.68. At this price rate, how much would 10 erasers cost?​

$5.60

Step-by-step explanation:

1.68/3 = .56

10 x .56 = 5.6

$5.60

Step-by-step explanation:

1.68 / 3 = 0.56

This is the cost of one eraser.

Now, to find the cost of ten, all we have to do is:

0.56 x 10 = $5.60
