Answer 1

Hope this helps but I think the answer is $50

Answer 2

Total amount paid by Matt at restaurant was 55 dollars. It included a service tip of 10% on check amount.

Total bill is given by sum of check amount and tip amount (if any).

Total Bill = Check amount + Tip amount.

55 dollars = Check amount + 10% of check amount.

55 dollars = 110% of check amount.

55 dollars = 1.10 x check amount.

Check amount =
`(55 \;dollars)/(1.10) = (550)/(11) = 50 \;dollars.`

Hence, option D is correct, i.e. 50 dollars.
