Sam and Martha had a total bill (including tax) of $29.32 at The Spaghetti House restaurant. They also purchased 2 shirts for $19.98 each (not including tax) from a nearby clothing store. Part A: They wished to leave a tip of 18% at The Spaghetti House. How much total money did they spend at the restaurant? (Round to the nearest cent.)

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1.35x+1.08y=104.49.

3. solve the system of two equations:
