D. Multiply the price of each item by 0.9
E. For each item, divide the price by 10 to find 10% of the item and then multiply that quotient by 11 to find 110% of the origional price.

Answer 1

Answer:

Step-by-step explanation:

B is correct as 1.1 = 110%

C is correct as adding (0.1 multiply original price) = 1.1 = 110%

E is correct as dividing original price by 0.1 then multiplying by 11 = 1.1 = 110%

Answer 2

Correct Answer: B, C

Choice A only finds the amount that is increased by, not the new price

Choice D is if the original price is discounted by 10%

The second part of Choice E does not make sense

Basically, here is how you find the new price:

Let the original price be x.

New Price = x * (1 + 10%) = x * (1 + 0.1) = x * 1.1
