x = 1.50 + y
*40x + 40y = 940
40 (1.50 + y) + 40y = 940
60 + 40y +40y = 940
60 + 80y = 940
80y = 940 - 60
80y = 880
y = 880/80
y = 11
*x - y = 1.50
x - 11 = 1.50
x = 1.50 + 11
x = 12.5

<h2>Hello!</h2>
The answer is: 50% (0.5)
<h2>Why?</h2>Exponential growth equations are use to predict the growth (in function of time) using proportional information.
We can calculate the exponential growth using the following formula:
Where,
S, is the starting value
r, is the growth rate
t, is the time
So, we are given the function:
Where,
f(t), is the function,
3, is the starting value (lb)
0.5 (50%) is the growth rate
nt, is the time elapsed.
Hence,
From the given function, we know that the growth rate is equal to 0.5, and it's equal to 50%.
We can turn the growth rate given in real numbers to percent value by multiplying by 100
So, the growth rate is 50%.

They made profit of by selling 190 kg of taffy in 400 g bags at rate of
each.
<u>Solution: </u>
Given that
To raise money, the Boy Scouts bought 190 kg of taffy for .
They sold the tafty in 400 g bags for
Need to calculate the profit the made.
Cost price of 190 kg of taffy =
As 1 kg = 1000 gram,
So 190 kg of taffy =
So cost price of 190000 gram of taffy =
Now let us calculate number of 400 grams bags which can be made from 190000 grams of taffy
Number of 400 grams bags =
Amount generated from 1 bag of 400 gram taffy = 3.28
So amount generated from 475 bags of taffy =
Selling price of 190000 grams of taffy = amount generated from 475 bags of taffy =
Hence they made profit of by selling 190 kg of taffy in 400 g bags at rate of
