Answer:
The original price was $2.
Step-by-step explanation:
The muffin is on sale for 5% off. This means it is being sold for 95% of its original price.
Its sale price is $1.90. This means that 95% of its original price is 1.90.
Let's set up an equation.
95% of original price is $1.90.
0.95 • x = 1.90
Divide both sides by 0.95 to isolate x.
x = 2
The original price was $2.

Answer: The average rate of change is ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
The points (1, 2); (2, 2.5); (3, 3); (4, 3.5) and (5, 4) belong to the line shown in the graph attached.
The average rate of change for the sequence is the slope and you can calculate it with the formula:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Then, choose two points of the line and substitute them into
:
Let's choose the point (1,2) and the point (2,2.5). Then:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![m=\frac{2.5-2}{2-1}\\\\m=\frac{1}{2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B2.5-2%7D%7B2-1%7D%5C%5C%5C%5Cm%3D%5Cfrac%7B1%7D%7B2%7D)
Hope this helps.
In the second problem, because 3 is not large enough to subtract 6 from, change 4 to 3 and add 1 before 3 to get 13-6.
God bless!!! xx
