Answer: $7.525
Step-by-step explanation:
A markup is an amount that is added to the cost price of an item in order to get a sell price that is used to make a profit.
Cost price= $3.50
Markup = 115% = 115/100 × 3.50
= 1.15 × 3.50
= 4.025
Selling price= Cost price + Markup
= $3.50 + $4.025
= $7.525
A customer will pay $7.525 for the item.

Answer:
4) 7.9%
Step-by-step explanation:
Given:
% of milk chocolate = 70%
% of white chocolate = 30%
Total number of chocolate = 20
Number of milk chocolate:

Number of white chocolate:
From the calculations, we now know there are 14 milk chocolates and 6 white chocolates.
2 white chocolates are picked at random without replacement.
Probability first chocolate picked was white: 
Probability second chocolate picked was white: 
To find probability that both of them are white chocolates, multiply probability of the first and second.
0.3 * 0.2632 = 0.07896
≈ 0.079
Convert to percentage by multiplying by 100.
0.079 * 100 = 7.9%
The probability that they are both
white chocolate is 7.9%
