Answer:
Step-by-step explanation:
Assuming simple interest,
45 = P * 0.03 * 2
P = 45 / 0.06 = $750
First find the slope, (y2-y1)/(x2-x1)=(20-10)/(40-20)=10/20=1/2
y=mx+b, where m is the slope and b is the y-intercept
y=x/2+b, using any point we can solve for b, I'll use (20, 10)
10=20/2+b
10=10+b
0=b, so the cost function is:
C(m)=m/2 (cost in dollars as a function of minutes is minutes divided by two)
N+(n+1)=293
2n+1=293
2n=292
n=146
n=146, n+1=147
146+147=293
Answer: she used 11/168 tank of gas per mile
Step-by-step explanation:
12 miles___11/14 tank of gas
1 mile____x= 11/168 tank of gas
(1 mile * 11/14 tank of gas)/12 Miles=
11/168 tank of gas
