Number of cartons in case of Scout cookies = 10 cartons
Number of boxes in carton of Scout cookies = 12 boxes
Amount earned on whole case = 10(12x) dollars
To simplify the expression, we will multiply 10 by 12x
Amount earned on whole case = 120x dollars
Simplified expression: 120x dollars

Answer:
1/3 = 4/12
1/4 = 3/12
Step-by-step explanation:
1/3 * 4/4 = 4/12
1/3 = 4/12
1/4 * 3/3 = 3/12
1/4 = 3/12
1) you would need to turn both fractions so they have a common denominator, that would be 2 2/4 and 3/4
2) then subtract : 2 2/4 - 3/4, and you would subtract numerators and the whole number, but you keep the denominator the same. However, you cannot subtract 2 and 3 in this case, so you need to change 2 2/4 to 1 5/4 (they are still equivalent)
3) 1 5/4 - 3/4 = 1 2/4, which simplified version is 1 1/2
Therefore, the answer is 1 and 1/2
Answer:
-13c-4
Step-by-step explanation:
The original price is 100% of the price. If the price is marked 60% off, then you pay 40% of the original price.
An item costs x dollars.
With the 60% off discount, it now costs 40% of x, or 0.4x.
Now you apply a 30% discount.
For the second discount, consider the price 0.4x to be the new original price. If the price is now discounted 30%, you will pay 70% of the new original price.
Start with 0.4x.
Now calculate 70% of 0.4x.
70% of 0.4x = 0.70 * 0.4x = 0.28x
After applying the 60% discount and the 30% discount, the item that originally cost x now costs 0.28x. 0.28x is the same as 28% of x. The amount you pay is 28% of the original price.
Answer: 28%
