She would make 3.00 dollars
50(10) - 20(10) = (10)(50 - 20)
500 - 200 = (10 * 30)
300 = 300
(10)(50 - 20) = 30(10)
(10 * 30) = 300
300 = 300
If RS is congruent to MN then the value of x in all the parts are 6,4, and 10.
Given RS is congruent to MN.
We are required to find the value of x if RS is congruent to MN.
Congruent lines are those lines whose lengths are equal to each other.
1) RS=x+10, MN=2x+4.
Because the congruent lines have equal lengths so , RS=MN.
x+10=2x+4
x-2x=4-10
-x=-6
x=6
2) RS=3x-2, MN=x+6
Because the length of lines are equal,so RS=MN.
3x-2=x+6
3x-x=6+2
2x=8
x=4
3) RS=5x-10, MN=2x+20
The lengths are equal so RS=MN.
5x-10=2x+20
5x-2x=20+10
3x=30
x=10
Hence if RS is congruent to MN then the value of x in all the parts are 6,4, and 10.

It is not because 30×10^4 is 300,000.
The answer would then be...
30×10^5
Hope this helps!
Answer:
B
Step-by-step explanation:
They all separately bought items therefore the number of items will be discrete. But they spent the same time all together,therefore total time will be continuous.
