Answer:
200 miles
Step-by-step explanation:
First, set up the equations.
plan 1: initial fee of $55.96, $0.12 per mile
plan 2: initial fee of $63.96, $0.08 per mile
We want to know at what distance will the cost be the same. So, set the equations equal to each other.
0.12x + 55.96 = 0.08x + 63.96
Combine the variables.
0.04x + 55.96 = 63.96
Combine the constants.
0.04x = 8
Divide by 0.04 to isolate x.
x = 200 miles
Check by plugging x back into each equation.
y = 0.12(200) + 55.96
y = 24 + 55.96
y = $79.96
y = 0.08(200) + 63.96
y = 16 + 63.96
y = $79.96
You are correct!
Answer:
the correct answer for this question is
2/5/3/2
-2 sqrt (20) -sqrt (125)
-2 sqrt (4 * 5) - sqrt (5 * 25)
-2sqrt (4) * sqrt (5) - sqrt (5) sqt (25)
-2 * 2 * sqrt (5) - 5sqrt (5)
-4sqrt (5) -5sqrt (5)
-9sqrt (5)
511 divided by 7 is the unit rate. So a is how you get it but d is the answer
