Answer: $104
Step-by-step explanation:
First you have to find 30% of 80. If 100% is 80, then 10% is 8. To get 30%, multiply 8 by 3 to get 24. So if 30% of 80 is 24, and you need to find the new price of the shoes because they were marked up 30%, then add 24 to the original priceof 80. $80+$24=$104
Answer:
y = 3 and y = x + 3
Step-by-step explanation:
The equation y = 3 whose graph is a line parallel to x-axis can be a part of the system.
Consider the equation y = x + 3.
Substitute (0, 3).
3 = 0 + 3
So, (0, 3) lies on y = x + 3 and this can also be a part of the system.
