Answer 2

1050

Explanation:

We can use a ratio to solve

First find how many jam

210 - 189 =21

We want to find how many jam for 10500 printed

21 jam x jam

----------- = ----------------

210 printed 10500 printed

Using cross products

21 * 10500 = 210x

Divide each side by 210

21*10500/210 =x

1050=x
