Joyce paid $220 for an item at the store that was 35 percent of the original price. What was the original price?
allochka39001 [22]

Answer:

The original price of item was $ 628.57

Step-by-step explanation:

Given as :

The amount paid fro an item = $ 220

And The paid amount was 35 % of the original price

Let The original price be x

So, According to question ,

35% of original price = $ 220

Or, 35% of x = $ 220

Or,    x = \frac{220\times 100}{35}

Or,    x = $ 628.57

Hence The original price of item was $ 628.57    Answer

I need to understand the solution.
Anika [276]

Answer:

A

Step-by-step explanation:

Rules:

odd x odd = odd

even x even = even

even x odd = even

even + even = even

odd + odd = even

odd + even = odd

We can determine whether 2a + 3b is odd if we have both statements because we know that a is odd and 2 is even, which means their product will be even. 3 is odd and b is odd, so their product will be odd. The sum of the even and odd will be odd.

If we have just the second statement we can determine the answer because anything multiplied by 2 is even.

So whether or not we know if a is odd, we know that 2a is even because 2 doubles everything which means it's divisible by 2 which means it's even.

However, statement 1 alone is not enough because if a is odd, then 2a is even. However, 3b can be even or odd depending on b. If b is odd, then 3b is odd. if b is even, 3b is even.

Therefore, if you have statement 2 you can answer the question but if you only have statement 1 then you also need statement 2
