If it looks like this
y = 161*(0.725)^t then it's a decay. Reason: the base is under 1. Try a couple of values for t say 0,1,2

y = 161 * (0.725)^0 
y = 161

y = 161 * (0.725)^1
y = 161 * 0.725
y = 116.7

y = 161 * (0.725)^2
y = 161 * (0.5256
y = 84.63

You can see that the function is steadily getting smaller. Remember if the base is under 1 and more than 0 the function decays. If it is greater than 1 then the function grows.

Just to make sure we understand what I'm saying
0 < base < 1
y = a ( base)^power.

What is the answer some one help me please so i can do this
inna [77]

Answer:

They can buy up to 240 drinks.

Step-by-step explanation:

Let x = number of drinks

The price of 1 drink is 75¢ = $0.75

The price of x drinks is 0.75x

The store gives a discount of $100.

The rice of x drinks is

0.75x - 100

The total price of the drinks must be less than or equal to $80.

0.75x - 100 ≤ 80

Add 100 to both sides.

0.75x ≤ 180

Divide both sides by 0.75

x ≤ 240

Answer: They can buy up to 240 drinks.
