Part A
Commission total = Commission 1+ Commission 2
Where
Commision 1 = 5% of first 45000
Commission 2 = 7.5% of the amount left after $5000 is subtracted
thus
Commision 1 = $5000x.05
= $250
Commission 2= $3000 x.075
= $225
Commission total = $250+$225
= $475
The total commission she earned is $475ion
Part B.
Total sales = Sales with 5% commission+Sales with 7.5% commission
Sales with 5%commission= $5000
Commision At 7.5% = Total commision -Commission with 5%
= $1375-$250
Sales x.075= $1125
Sales with 7.5% commision = $15000
Total sales = $5000+$15000
Total sales = $20000
Total sales for commission of $1375 is $20000

Answer:
The answer to your question is 43.7 g of chocolate
Step-by-step explanation:
Data
56% cocoa
mass of a chocolate bar = 78 g
Process
To solve this problem, use proportions and cross multiplication, consider the mass of the bar is 100%.
78 g of chocolate ------------------- 100%
x ------------------ 56%
x = (56 x 78) / 100
x = 4368/100
x = 43.68 g
-Round to the nearest tenth
Mass of the chocolate = 43.7 g
