So here:

Sum of of observations =6+ 10+ 6+10+11+12+12+13+12+0+ 5+ 4+ 8+ 0+7=116

Number of observations = 15

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary
11111nata11111 [884]

Answer:

She earned 1,076 dollars and 25 cents.

Step-by-step explanation:

x =  7.25 * 4,500 / 100

x = 7.25 * 45

x = 326.25

So commission earned is 326.25 $

We need to add this to her base salary for the week, so:

750 + 326.25 = 1, 076.25

Therefore she earned 1,076 dollars and 25 cents.

Hopes this helps ;p
