Considering her change, it is found that she will donate $0.28 to the animal shelter.
<h3>How to find the amount of change in a purchase?</h3>
The amount of change is given by the subtraction of the total paid and the price of the products.
In this problem, the price of the products bought is given by:
$15.74 + $3.98 = $19.72
She paid $20, hence the change is given by:
$20 - $19.72 = $0.28.

Answer:
Step-by-step explanation:
Let
x -----> the number of hours
y ----> the total cost to rent a bike in dollars
we know that
The equation of the line in slope intercept form is equal to
where
m is the slope or the unit rate of the linear equation
b is the y-intercept or the initial value
In this problem we have
The unit rate or slope is equal to
The y-intercept (value of y when the value of x is equal to zero) is equal to
----> (fee charge)
substitute the values
43/50 is easier because 50 is half of 100
Watch this
43/50. Since 50 is HALF of 100 so we multiply 2 by 50 which is 100. But since we multiplied by 2 for the denominator we have to do the same for the numerator so 43 x 2 is equal to 86.
So we get 86/100 which is 0.86
You would use the function root(Xsub2-Xsub1)^2+(Ysub2-Ysub1)^2.
Now plug in your numbers.
This gives you root(7-1)^2+(5-(-3))^2.
Simplify to root(6)^2+(8)^2. Simplify again to root36+64.
Simplify one more time to root 100. now solve.
Your answer is 10.
A is the answer since if you graph it, it has those points, or you may just simply plug in the x points that are given and see if they equal the y number
