Answer:
The answer is below
Step-by-step explanation:
a) Natalie basic salary is $300 per week. She is paid a commission of 30% of her total sales for the week. Therefore her total weekly salary per week is given by:
Total weekly salary = Basic salary + Commissions
If Natalie makes $225 in sales, her commission = 30% of $225 = 0.3 × $225 = $67.5
Total weekly salary = Basic salary + Commissions = $300 + $67.5
Total weekly salary = $367.5
b) If Natalie makes $x in sales, her commission = 30% of $x = 0.3 × $x = $0.3x
Total weekly salary = Basic salary + Commissions = $300 + $0.3x
Total weekly salary = $(300 + 0.3x)
3,868,000,000 in scientific notation is 3.868*10^9

Answer:
Step-by-step explanation:
-1 to 0 is divided in four parts.
similarly 0 to 1 is divided in four parts
so each fraction on either side is 1/4 onthe right of 0 and -1/4 on the left of 0.
A is 2 parts on the right of 0,A=2×1/4=1/2=0.5
Bis 1 part left of 0,B=1×(-1/5)=-1/5=-0.2
