Answer:
f = 65
Step-by-step explanation:
6.50*21+f=201.50
We need to isolate f
1. multiply 6.50 by 21. 6.50 * 21 = 136.5
136.5+f= 201.50
2. Since 136.5 is positive and not being subtracted we will...
Subtract 136.5 from both sides
136.5-136.5=0+f
201.50-136.50 = 65
thus leaving f = 65
I'm assuming she gets 2% commission on sales and that she gets paid monthly from her yearly salary.
If the above is true, her monthly pay is calculated as follows:
Commission: 48500 * 0.02 = $970
Monthly salary: 30000 ÷ 12 = $2500
So monthly pay is $2500 + $970 = $3470
9514 1404 393
Answer:
The CPI increased 3.42% in Month 2.
Step-by-step explanation:
In a spreadsheet, the weighted sum is easily computed using the SUMPRODUCT( ) function. It multiplies the corresponding values of two arrays, then returns the sum of those products. If one of the values is a weight, then the result is a weighted sum.
Your CPI is computed as the weighted sum of the prices of the individual products. The percentage change is computed in the usual way:
pct change = ((new value)/(old value) -1) × 100%
Of course, the spreadsheet can format a fraction as a percentage, so the computation of the change can stop after 1 is subtracted from the ratio.
Sigma(i = 7 to 16, 2i-12) = 2*sigma(i = 7 to 16, i) -120
= 2*115-120 = 110
