Tye key word is EACH and that means to multiply, and when a 7 is touching a variable or in our case x, it means to multiply.
Since she travels x miles a day, she will travel 7x miles a week because there are 7 days a week
$125
Since there are 12 months in a year, divide the total bill by the total number of months.
1500/12 = $125
Using log properties
Then
Plug in the knowns
22
20 + (-45) = -25
18% = 0.18
Tip = $36.00 x 0.18 = $6.48
Total bill = $36.00 + $6.48 = $42.48
Total bill = $42.48
Tip = $6.48
