Answer:
y8
Step-by-step explanation:
Answer: The fraction 301/900
Note: I'm assuming the 4's continue on forever
==============================================
Work Shown:
I'm going to assume that the 4s go on forever. I'll represent this with three dots after the last 4 like so
0.334444...
Now let x = 0.334444...
Multiply both sides by 100
x = 0.334444...
100x = 100*(0.334444...)
100x = 33.444444...
And repeat with 1000
x = 0.334444...
1000x = 1000*(0.334444...)
1000x = 334.444444...
Then subtract and solve for x. Notice how the decimal parts line up and cancel
1000x-100x = (334.444444...) - (33.444444...)
1000x-100x = (334+0.444444...) - (33+0.444444...)
1000x-100x = 334+0.444444... - 33 - 0.444444...
1000x-100x = (334-33)+(0.444444... - 0.444444...)
900x = 334 - 33
900x = 301
x = 301/900
y = total cost
x = amount of toppings
z = # of patties
y = 4z + 0.75x
For one burger with 1 topping, the equation becomes y = 4 + 0.75
1 topping: $4.75
4 toppings: 4 + (0.75 x 4) = $7
6 toppings: 4 + (0.75 x 6) = $8.50
10 toppings: 4 + (0.75 x 10) = $11.50
Answer:
100+70+8+0.2+0.05. is the answer
