60*80/100-$10*155/100
48-$10*155/100=$58.90
Answer:7
Step-by-step explanation:
Answer:
y = 3 + 0.40x
Step-by-step explanation:
Fixed cost of taxi fare = $3
Additional cost = $0.40
Let
y = Total cost
x = number of kilometers
The equation:
Total cost = Fixed cost of taxi fare + (Additional cost * number of kilometers)
y = 3 + 0.40x
Subtract what is to the right of the equal sign form both side of the equation but any way the answer is 0
Slope intercept form:
y=mx+b
m=slope
b=y-intercept:
We Know the slope (m=2)and we have a point (4,2) then:
x₀=4
y₀=2
we have to find "b"
y=mx+b
2=2(4)+b
8+b=2
b=2-8
b=-6
Therefore:
if b=-6 and m=2; the equation in slope intercept form would be:
y=2x-6
