Answer:
13.3
Step-by-step explanation:
There is an equation that helps
mean= (All of the numbers in the data added) divided by (the number of numbers in the data)
What that mean is:
1.) Add 20, 5, 7, 17, 16, and 15
2.) divided by 6 (because there is 6 numbers in the data)
3.) round it to the nearest number (numbers from the one's place being 4-0 means go back or 5-9 means go forward a number)
which in this case it should be 13.33333...=13.3
Answer:
The cost of dinner alone was $37.145
Step-by-step explanation:
15%=0.15----Convert your percentage into a decimal
43.70*0.15=6.555----Multiply the cost of dinner with the decimal
$43.70-$6.555=$37.145----Subtract the last number(6.555) from the total(43.70) to get the cost of dinner alone of $37.145 -This is making you subtract the percentage from the total!
I hope this helped!
