Sally bakes 80 cupcakes for a bake sale. She sold 4 cupcakes and earned $8. How much money can she earn if she sells all the cupcakes.
Answers
4/8 = 1/5 = .50
That means each cupcake equals $0.50.
Now, multiply
80 * .5 = 40
Answer: Sally would earn $40 if she sells all the cupcakes
TO find out how much she would earn for 80 cupcakes we will find the unit rate for the amount she sold and how much she earned. Lets do it:-
8/4 = .50
$0.50 per cupcake
0.50 * 80 = 40
So if she sells 80 cupcakes she will earn $40.

What is a trick for multiplying 9`s
Answers
A trick that is good for multiplying 9's is, remember that each time the tens digit changes the number in the ones spaces minuses 1. If you don't understand what I am saying look at the following:-
9 18 27 36 45 54 63 72 81
See the pattern? In the tens place you need to add 1 and in the tens place you need to subtract by 1.
Hope I helped ya!! xD
This works for 9 times 1 through 9 times 10. You can take the number that is times 9 and and minis the number by one. Then you think about what number plus the first number ( the number that is times 9 and and minis the number by one) equals 9 and that number goes in the tens place. If you don't understand then look at this: 9×1=09 9×2=18 9×3=27 9×4=36 9×5=45 9×6=54 9×7=63 9×8=72 9×9=81 9×10=90
Is my answer correct? Even if it is tell me so. If it is not, explain the correct answer to me..
