The tip Lamar left is 18% of the total bill, which is $45.

Tip amount = 18% of $45
Tip amount = 0.18 * $45
Tip amount = $8.10

Therefore, Lamar left a tip of $8.10.

To calculate the total cost of Sarah's dinner including tip, we first need to calculate the amount of the tip she left.

Tip amount = 18% of $90
Tip amount = 0.18 * $90
Tip amount = $16.20

Now, we add the tip amount to the total bill to get the total cost of her dinner.

Total cost = $90 (bill) + $16.20 (tip)
Total cost = $106.20

Therefore, the total cost of Sarah's dinner, including tip, is $106.20.

To calculate the amount of the mark-up, we first need to determine the value of the mark-up.

The mark-up percentage is 41%, so the mark-up amount is 41% of the store's cost for the golf clubs:

Mark-up amount = 41% of $942
Mark-up amount = 0.41 * $942
Mark-up amount = $386.22

Therefore, the amount of the mark-up on the golf clubs is $386.22.
