    ✅Thanks so much for watching! ✌✌✌
    ⚠IMPORTANT NOTES WHEN WORKING WITH DISCOUNTS AND SALE PRICES⚠
    ✅This video used US currency in the examples, but discounts and sale prices can be calculated using this method with other currencies as well.
    ✅Money always goes to the hundredths place when we have change. For example, #1 gives us an answer of 10.2 when we multiply 68 x 0.15. I wrote the discount as $10.20 because money goes to the hundredths place when we have change. $10.2 does NOT mean $10 and 2 cents, it means $10 and 20 cents, so we write it as $10.20. On the other hand, if you get a decimal that goes past the hundredths place, for example 15.83845, then it needs to be rounded to the hundredths place. That decimal would round to $15.84. Something to keep in mind.

      Hey, when doing the discounts for the second one how do you set it up. Where do you put the number where you multiply since it has extra digits?

    @Leusiom1 2 ปีที่แล้ว +70

    For an easier explanation:
    1. Covert the percentage to a decimal form by moving the decimal to the left twice.
    2. multiply them
    3 with the multiplication answer, minus it from the original price.

    Mr. J, I'm in grade 6 and my final math exams are TOMORROW! But... YOU ARE A LIFESAVER! You know why? Well, it's because.... YOU ARE THE BEST TEACHER EVER MY TEACHERS ARE BAD BUT YOU ARE SO GOOD I LEARNED ALL SUBJECTS FOR MY FINALS IN LESS THAN 30 MINUTES!! That's literally how long it takes my teacher to teach one lesson... Good thing you exist because if not, I would fail math and go to summer school OR not make it to high school!!

    Thank you so much! I was so bad at Sale prices in my math tuition that the tutors were going to tell my parents that they are going to give me one more test, and that determines weather I stay at the tuition or I get kicked out. And my parents would be really mad and disappointed if I get kicked out so I watched this video and the next day I done the test I got 100%! Thanks so much J!♥
