Question

Last night, 4 friends went out too dinner at a restaurant. They split the bill evenly. Each friend paid $12.75 for his or her meal and each left the same amount for a tip, t. The total dinner bill including the tip was $61. What equation could you use to describe the situation?

Answer 1

Answer:

4(12.75 + t) = 61

Step-by-step explanation:

4 x 12.75 gives you 51

If you subtract 51 from 61 then you get 10.

That leaves the 4 tips at $10.

Now we have to divide 10 by 4.

10/4 = 2 1/2

2 1/2 = 2.5

Each friend tipped $2.5.
