Answer:
$0.1 is the additional fee per mile.
Step-by-step explanation:
Given:
Fixed charge = $35.99
Total Bill charged = $90.99
Number of miles traveled = 550 miles
Let additional fee per mile be x.
Now total bill Charge = Fixed charge + additional fee per mile × Number of miles traveled
The expression can be represented as;
Hence, the additional fee per mile is $0.1.
Step-by-step explanation:
step 1. (5/3)^(-5) x (5/3)^11 = (5/3)^(-5+11) = (5/3)^6
step 2. (-2/5)^7 ÷ (-2/5)^5 = (-2/5)^7 x (-2/5)^(-5) =(-2/5)^(7-5) = (-2/5)^2.
