2 answers:
4 month
Find the average of last 4 month
Find mean
Sum of Numbers divided by the count of numbers
92+ 28+ 28 +75 divided 4
278 divided by 4
69.5
If 4month = 69.5
x. =. 71
Cross multiply
69.5x =71 *4
69.5x.= 284
Divide both side by x
x= 284 / 69.5
x= 4.08 to whole number
x = 4 months
Answer: 77 suits
Step-by-step explanation:
Let sales of this month = x
Sales for last 4 months = 92, 28, 83, 75
Average = Sum of Observation ÷ No of Observation
Now, we can form an equation
(92+28 +83+75+x) ÷ 5 =71
(92+28 +83+75+x) = 71 × 5
278 + x = 355
x = 355 - 278
x = 77

7n-2n+3p+2p
5n+5p (combine like terms)
the answer is 5n+5p
(Its 17 of them actually)
p=percent
17/25=p/100
So 25*4=100.
so that means that we need to multiply the numerator 17 by 4 also. 17*4=69.
So, they won 68% of their games.
Hope this helps :^)
