Susan tips at the rate of $65 to 5 waiters. If she can afford a $90 tip, then she would be tipping 7 waiters? Explain your reasoning.

Respuesta :

No she would not be tipping 7 waiters. This is because for every waiter she tips $13.00 shown by 65/5=13. If she wanted to tip 7 waiters at the same rate she would need $91.00 shown by 7*13=91.00.
