Answer:
325 miles and 77 dollars
Step-by-step explanation:
First, create equations. Let x equal the miles driven. The first plan expression is 38 + 0.12x and the second plan expression is 51 + 0.08x. Setting these equal and solve for x: 38 + 0.12x = 51 + 0.08x -> 0.04x = 13 -> x = 325 miles.
The cost is found by substituting it into any of the expressions: 51 + 0.08(325) = 77 or 38 + 0.12(325) = 77

Answer:
$24.7875
Step-by-step explanation:
Step one:
given data
your bill before taxes and tip is $19.83
6% sales tax
tip equal to 19% of the original amount.
Required
The total expenses
Step two:
let the total expenses be y
let us calculate the cost of tax and the tip
Tax
=6/100*19.83
=0.06*19.83
=$1.1898
Tip
=19/100*19.83
=0.19*19.83
=$3.7677
Total
Y= 19.83 +1.1898
+3.7677
Y= $24.7875
