Answer:
(a) 25 miles
(b) $225
Step-by-step explanation:
Let the price charged be P and distance be d
For truck A
P=7d+50
For truck B
P=2d+175
When two trucks charge the same, P for A and B are equal hence
7d+50=2d+175
Combining like terms
7d-2d=175-50
5d=125
d=125/5=25
The distance is 25 miles
The amount will be
For truck A
P=7(25)+50=$225
For truck B
P=2(25)+175=$225
