Answer:
116,200 km
Step-by-step explanation:
Here we have 2 cars, each one with it's corresponding costs. Let's write each cost as functions. The SUV costs $27,070 plus $0.018 per mile. Let x be the miles and SUV (x) the SUV's cost:
SUV(x)=27070+0.18x
We can do the same for the hybrid with a cost function H(x):
H(x)=32880+0.13x
We now need the cost of the SUV to be greater than the hybrid. This is SUV (x)> H(x):
27070+0.18x > 32880+0.13x
Let's subtract 27070 in each side:
0.18 x > 32880 - 27070 + 0.13x
Now let's subtract 0.13x in both sides:
0.05x > 5810
Divide both by 0.05:
x > 5810/0.05
x > 116,200
So, after 116,200km the SUV will turn to be more expensive.
