1. $21

2. $56

Step-by-step explanation:

1.

100% - 30% = 70%

70% * $30 = 0.7 * $30 = $21

2.

100% - 20% = 80%

80% * $70 = 0.8 * $70 = $56

Step-by-step explanation:

The equation for percentages is (percent over 100) times (x over total)  

So for the table the equation is 30/100 * x/30

You cross multiply your total x percent and divide by 100.

So 30 * 30 = 900

900 / 100 = 9

30% of 30 is 9.

Now subtract your answer from the original total (30 - 9 = 21)

So the sale price of the tennis table is $21.

Now repeat for your other equation

Your equation is 20/100 * x/70

So 20 * 70 = 1400

1400 / 100 = 14

20% of 70 is 14.

Now subtract your answer from the original total (70 - 14 = 56)

So the sale price of the easel is $56.
