How to Calculate a Discount and Sale Price | Math with Mr. J

✅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.

this helped me so much and tom is my test

Diss video suggz

Thank you Mr.j for helping and im sure I will ace that test tomorrow

u are goiod

Thank you very much

I need to take the asvab. This doesn’t help me when your using a calculator

welcome to math with mr j

To do it in your head is real simple. Use the 40 percent off example and figure it like this. Use ten percent off the price and multiply it times four. 10 percent off of 219.95 is 21.99. "simply move the decimal point one over" I round it to "22" x 4 = 88 off. "NO PAD, PENCIL OR CALCULATOR"

i just subscribed to you because you finally helped me no one else cannot explain it better than you 😁😁🫶🏼🫶🏼🫶🏼
