Answer:
73.2
Step-by-step explanation:
76+66+55+80+80+72+97+70+80+72+88+50+63+76 =1025
Mean = 1025/14
= 73.2
73.214285714285714285714285714286 (or 73 rounded down)
76, 66, 55, 80, 80, 72, 97, 70, 80, 72, 88, 50, 63, 76
76 + 66 + 55 + 80 + 80 + 72 + 97 + 70 + 80 + 72 + 88 + 50 + 63 + 76 = 1025
1025/14 = 73.214285714285714285714285714286
73.214285714285714285714285714286 ≅ 73
Mr. Chan's total account receivable is of $212,500.
$85,000 this month this represents 40% of our receivables
This means that 85000 is 40% = 0.4 of the receivables, which is x.
What is mr. Chan's total account receivable?
We have to find x
625 miles
250/4=62.5
62.5*10 = 625
Find two numbers with a sum of 20 and a difference of 14
Make two equations
X+Y=20
X-Y=14
Now add x since y cancels out and add 20+14 To end up with
2x=34
Now divide 2 both sides to get x alone
2x/2=34/2
X=17
Now substitute x answer to first equation and solve for y
17+y=20
Subtract 17 both sides
Y= 3
Your two numbers are
3 and 17
