Answer:
a). Nadia made a total of $825 last week in commission sales
b). The total amount Nadia in commission in 2011=$42,900
Step-by-step explanation:
Step 1
Express the amount in commission she earns from her sales as follows;
C=S×r
where;
C=commission earned
S=total value of stock sales
r=commission rate
In our case;
C=unknown
S=$7,500
r=11%=11/100=0.11
replacing;
C=11% of 7,500
C=(11/100)×7,500
C=0.11×7,500=825
Nadia made a total of $825 last week in commission sales
b). To express the total amount she made in 2011, we derive the formula below;
Total amount (2011)=Average weekly commission×number of weeks in 2011
where;
Average weekly commission=$825
number of weeks in 2011=52
replacing;
Total amount (2011)=(825×52)=42,900
The total amount Nadia in commission in 2011=$42,900
Substitute the given value into the function and evaluate.
The answer is -10
Answer:
Step-by-step explanation:
Koris current age = x
Josephs current age = 7 + x
Koris age after four years = x + 4
Josephs age after four years = 7 + 4 + x = 11 + x
In 4 years the sum of their ages will be 75.
So, (x + 4) + (11 + x) = 75
= 2x + 15 = 75
2x = 75 - 15
x = 60/2 = 30
Therefore koris current age = 30
Josephs current age = 30 + 7 = 37
Hope this helps . Have a nice day!
