Answer:
It would be 10 months for the price of $320.
Step-by-step explanation:
First we need to find how much Anna's swimming charge and Bobie's charge is.
PA=70+t The price of the month equals to the starting fee and monthly charge
120=70+2t The price of 2 months times the monthly charge
50=2t
25=t is Anna's monthly charge
PB=250+t is Bobies starting price and monthly charge
264=250+2t is the month charge for Bobie after 2 months
14=2t
7=t is Bobie's monthly charge
70+25x=250+7x We need to find x which is what month will satisfy both equations
25x=180+7x Subtract 70 from both sides
18x=180 Subtract 7x from both sides
x=10 divide 18 from both sides
Now we have the months that satisfy both equations we need to find the total price that matches with it. So we plug it back into both equations.
PA=70+25x PB=250+7x
PA=70+25(10) PB=250+7(10)
PA=70+250 PB=250+70
PA=320 PB=320
Answer:
I'm pretty sure it's 24.516
Answer:
about 154.3

Answer:
Step-by-step explanation:
Exponential functions grow at the fastest rate because the function increase or decrease in a power form.
for example, "2 raised x "means that when ever the power increase the number gets large and the same for decrements.
example: when x=1 it becomes 2
x=2 4
x=3 8
.
.
x=n 2∧n which a very big number.
In the same case it decreases dramatically if the power is negative or the number is improper fraction with positive number exponent; like (3/4)∧x,2∧-x when x is positive real number.
The similarities of both trend is that the change is the same both decrease or increase in similar scenario.
the difference is already known that one goes up with out bound but the one which decays goes down ward both with limitation and in unlimited cases.
