25 questions , because they start with 100. 350-100=250 .. 250/10=25

Answer:

Step-by-step explanation:

the fewest number you would have to answer to get 350 would be 25.

to get the fewest number you would not be able to miss any before reaching 350 points. since you are aiming for a minimum of 350 points and you start out with 100 you would divide 250 by 10 to get 25

Equation to find original price if sale price of $429 is a 34% discount
Burka [1]

Answer:

The original price is $650

Step-by-step explanation:

There's an actual algebra method for this, but this is my method because I find it way easier to remember.

Since the most you can discount out of an item is 100% (well, it's considered free then) let's subtract 100 - 34, which is 66.

Now, turn it into a decimal because it makes the numbers easier- 0.66.

Since when you're finding the discount of an original price, you multiply the original price by the discount- instead for finding the original price for a discounted item we divide $429 by 0.66 instead, since when you divide a number by another number that's under 1 the quotient is a larger number.

So, 429 ÷ 0.66 = 650.

Therefore, the original price of the $429 sale price for a 34% discount is $650.
