Answer: It would cost $16 dollars for 4hrs
Step-by-step explanation:
1. First find the value of the first two hours so $5.50+$5.50=$11
2. Then calculate how much for the last two hours, so $2.50+$2.50=$5
3. Combine the two $11+$5=$16 for 4hrs
Basically you just do $14.85•22% or .21 (they are both the same thing). When you do that you should get 3.1185. If you round that to the nearest cent then your answer is $3.12
Answer:
9 days
Step-by-step explanation:
1= 9*(1.04)^d
12.81/9= (1.04)^d
1.423= (1.04)^d
log(1.423)= d *log(1.04)
0.1532=d * 0.017
d= 0.1532/0.017
d=9
The reasonable domain to plot the growth function is in the interval [0,9].
