Answer:
b=12.50p
Step-by-step explanation:
Given :
x y
0 0
2 25
4 50
6 75
8 100
10 125
To Find: Which equation can be used to determine p, the cost of b boots?
Solution :
Using point slope form Find the equation of line of the given coordinates
Let 
Let 
So, formula : 


Now we are given that cost of b boots is p
Since we are given that x axis is Number of Boots and y in price
So in the equation put x = b and y = p
So, equation : b=12.50p
Hence Option 4 is correct
Step-by-step explanation:
2x-y=6 --------(1)
x+y=6 -------(2)
_____ Adding (1) and (2)
3x = 12
x=4
Substitute x on equation (2)
4+y=6
y=2
Answer:
Total amount earned = $84
Step-by-step explanation:
The correct expression is
Total amount earned = 80 + 4% of (t - 400)
= 80 + 0.04(t - 400)
where,
t = her sales total in dollars
Total amount of money that she will make for sales of $500
Total amount earned = 80 + 0.04(t - 400)
= 80 + 0.04(500 - 400)
= 80 + 0.04(100)
= 80 + 4
= 84
Total amount earned = $84
