My guess is B. hope i help
25% because if you simplify the fraction, it would be 1/4 and that is equal to 0.25
Answer:
y=0.8x+2.1
x= 12 miles
Step-by-step explanation:
Using the standard charge of 0.8 per mile and a fixed charge of $2.1. Let x represent the miles covered then the expression for coat at any given mile will be y=0.8x+2.1
Substituting $11.7 for y then we can find the valje of x as 11.7=0.8x+2.1
0.8x=11.7-2.1=9.6
X=9.6/0.8=12 miles
Initial charge charged by the Singer A = $50
Hourly charge of Singer A = $20
Initial amount charged by Singer B = $100
Hourly rate charged by Singer B = $10
Let us assume the time after which both singers will charge the smae amount of money = x
Then
50 + 20x = 100 + 10x
20x -10x = 100 - 50
10x = 50
x = 50/10
= 5
So after 5 hours both Singer A and Singer B will charge the same amount of money. I hope the procedure is clear to you and you can attempt such problems in future without needing any kind of help.
