- The cell phone costs $175
- she has already saved $56
<h3>To find:</h3>
- The percent of the cost of the cell phone has Jackie saved

- Multiply the result (1) by 100
See below how it's done:

dividing yields:

multiplying yields:

Alternative:
Instead of dividing,we can consider reducing the fraction and multiply that with 100 to get the answer.

In conclusion:
Jackie has saved 32% of the cost of the cell phone

Answer:
x = -6-2y
Step-by-step explanation:
Answer:
y = -1/2 x -5
Step-by-step explanation:
The slope intercept form of an equation is
y = mx+b where m is the slope and b is the y intercept
We know b
y = mx-5
Substitute the values of x and y into the equation to determine the slope
-2 = m(-6) -5
Add 5 to each side
-2+5 =-6m
3 = -6m
Divide by -6
3/-6 = m
The slope is -1/2
y = -1/2 x -5
