Answer: $18.19.
You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.
Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.
Answer: i think A
Step-by-step explanation:
Well,
The probability will be the number of favorable outcomes over the total number of outcomes.
The number of favorable outcomes will be the numbers greater than 4 (5,6) and the even numbers (2,4,6). So the favorable outcomes are 2,4,5, and 6. That is 4 total.
Eli is incorrect. The problem is he is correct on the exponent of 2 but he should have multiplied the the 6*5 to get 30 to the power of 2. But I guess go with A because he did get the power correct.
