Answer:This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25
Step-by-step explanation:
Answer:
x+2 < 14 | -2
x < 12
2+n <= 14 | -2
n <= 12
2+n < 14 | -2
n < 14
2+n >= 14 | -2
n >= 12
2+n > 14 | -2
n > 14
it affected more than half
