Answer:
Step-by-step explanation:
You are using the wrong accounting system
Forget the nine dollars.
If the thing bought was 25 dollars, then each one of A B and C put in 25/3 = 8.3333 dollars. If 1 dollar each was going back, then the sum became 9 1/3 dollars. 3 * 9 1/3 = 27 + 1 = 28. There is 2 dollars left. Everything is fine.
25 + 3 = 28
The three each got 1 dollar back. But the total accounted for is 25 + 3 = 28
There's 2 left over. That makes 30. Everything's fine. There is no missing dollar.
Answer:
868.065
Step-by-step explanation:
198.040 ÷ 98.1 + 100 x 4.3
= 2.0188 + 100 x 4.3
= 201.8756 x 4.3
= 868.065
34/100
= 0.34
3 tenths, 4 hundreths
Answer:
equation is the best model of the data: y=0.5x+2.4
Step-by-step explanation:
y=2.8(1.1^x)
try two points (2,3.5) and(1,3)
find m=y2-y1/x2-x1
m=3-3.5/1-2=
m=0.5
find b at point 1,3
y=mx+b
3=0.5(1)+b
b=3-0.5
b=2.5
Q: What is the equation of the exponential curve that passes through the points (0,3) and (5, 96)?
