Mr. Grinch: YOU ARE LATE ALAN!! NOW GET TO WORK!!!
Welcome to QuickMart!
Alan: *mumbles* I can't stand him. He's so bald you could see his reflection.
WHAT WAS THAT?!?!?!?!!
Nothing sir.......
Wendy: Hey, late again, I see!
Be quiet Wendy, you were late last week so you have no room to talk.
You're not the boss of me now. You're not the boss of me now, and you're not so BIG.
I could be your boss. I make more money than you. I make $9.75 an hour. How much do you make?
If you must know, I make $8.25 an hour. I bet I could make more money than you in one week. I'm Mr. Grinch's favorite.
I would like to see that happen...............huh!
Well, how about a little bet?? Whoever makes the most money in a week wins!
Deal! And the loser has to purchase and drink the most disgusting beverage at QuickMart.
I DON'T PAY YOU TWO TO SIT AND TALK. I PAY YOU YOU TO WORK! I heard you talking about a bet, do you guys even know how to solve problems using decimals???
No, we don't. Can you teach us?
Yes, will get lots of work done in the process. Its time to open the gas station so, get up and let's serve these customers.
Mr. Grinch explains how to multiply, divide, subtract, and add decimal numbers.
*,+,-,/........ 12.37,6.95.09.......
I hope you guys understood those concepts. Alan, you have a customer. Let's see if you can apply any of those concepts.
*thinks* Don't embarrass yourself
What's up dude! I'm ready to check out.
Tip: When adding decimals always put a "0" before the decimal point for numbers less than 1.
Hi sir, the cost of your items are as follows: Milk- $2.95, Sour Patch Kids- $.99, 32 oz Soda- $1.28, Peanuts- $4.57.
That sounds expensive, how much is that soda per ounce?
Tip: If the dividend is a decimal number, complete the long division procedure. Bring a copy of the decimal point straight up into the answer line.
Let me calculate it. *thinking* If you divide 1.28 by 32 then you get a decimal of 0.04. Sir, the 32-oz soda is 4 cents per ounce.
Ok, Great! How much do I owe?
Tip: Make sure the decimal points are directly lined up with each other
*thinking* To solve the problem, I need to stack the decimal numbers: 2.95 0.99 1.28 4.57
Your total is $9.79. If you have a chip, please insert your card and sign the keypad. Thanks for coming to QuickMart. We hope to see you again.
Great job Alan! You successfully multiplied and added decimal numbers. I see another customer walking in, Wendy wanna give it a shot??
You bet! I got this.
Hi! I'd like to pay for 12 gallons of Supreme Gas on Pump #3.
Tip: When multiplying decimals, pretend the decimal isn't there. Multiply like you regularly would and shift your decimal in the answer the same amount in the opposite direction.
Welcome maam! Each gallon costs $2.29 so that amount multiplied by 12 will cost you $27.48.
Good job! I'm a math teacher and I would be proud to have you as one of my students.
Tip: The order of numbers matter when subtracting decimals so, be sure that the number you're taking away is on the bottom.
Thanks! You gave me $30.00 in cash. If I subtract $27.48 from $30.00, your change would be $2.52. Have a Great Day! Come back to see us soon.
Wendy, you did just as well as Alan! You both learned how to solve real life problems using decimal numbers. The week has ended and here are your paychecks.
Tip: When dividing decimals, pretend the decimal isn't there. Divide like you regularly would and shift your decimal the same amount of times you shifted the decimal on the divisor.
NOOOO!!! I only earned $330.00 for 40 hours of work this week.
YES!!!!! I earned $292.50 for 30 hours of work this week!
Wait, so who won the bet??
I don't know. Let's use the concepts Mr. Grinch taught us and figure this out.
Alan's hourly pay is $9.75/hr and Wendy's hourly pay is $8.25/hr. If they both work 30 hours, Alan will still earn more because his hourly pay is $1.50 more than Wendy's.
Ok, Alan, you win! I lost the bet. Where is that disgusting drink? I want to forget this happened...
