Answer:
A. $58.50, B. $80
Step-by-step explanation:
mark up percentage 
x 100
30 x 45 = 100SP - 4500
5850 = 100SP
Store Price > therefore, $ 58.50
A. $58.50
<em>Actual Price :</em>
130 AP = 10400 - 100AP
AP > $80
B. $80
Answer:70.434
Step-by-step explanation:
First, we need to convert all the fractions to have the same denominator. 10 and 25 are both multiples of 100, so 100 would be appropriate.
Sam has a 7/25 chance. Because we want ?/100, something needs to change. To get from 25 to 100, you need to times 25 by 4, right? So, do the same with the 7.
7 x 4 = 28. Therefore Sam has a 28/100 chance.
Sue has 3/10. Using the same method, we can see that 3 needs to be multiplied by 10 (because 10 times 10 = 100). So Sue has a 30/100 chance.
Tom is already in the fraction we like, so just keep this as 21/100.
Now, add 28/100, 30/100 and 21/100 to get 79/100.
Because won of them will get the role of class president, we know that the probability adds to 1. To get a full probability (100/100, or 1), what needs to be added to 79/100?
Another way of going about this is 100/100-79/100. The answer is 21/100
The probability of Liz winning is 21/100.
Let me know if this is still unclear, I would be more than happy to explain in more detail if necessary :)
Answer: 2.127
Step-by-step explanation:
For this problem, we have to divide the number 212.7 by 100 cookies.
212.7 ÷ 100 = 2.127
So, each cookie will require 2.127 ounces of dough.
Sale price = $60
Discount = 20%
Regular price = $60/0.8 = $75
