Tom [10]

Answer:

Discount is $2.70

After-discount price is $15.30

Step-by-step explanation:

To get the after-discount price, multiply $18 by (1.00 - 0.15), or, in other words, multiply $18 by 0.85.  The after-discount price is $15.30.

Two ways to find the discount:  one is to multiply $18 by 0.15; the other way is to subtract $15.30 from $18.

Use mental math to find the sum of 432 + 250<br>​
GrogVix [38]

To start I would add 400 + 200, and that equals 600.

Then I would add 30 + 50, and that equals 80.

And then I have 2 left over.

600 + 80 = 680

Add the left over 2, so 680 + 2

680 + 2 = 682. Your answer is 682.

I hope this helps!
