Jack went out for dinner at Red Lobster, his meal was $45, jack wants to leave an 18% tip, list three different calculations jack can use to determine his bill including the tip

Step-by-step explanation:

Jack went out for dinner at Red Lobster and his meal was $45, This is the amount that he needs to pay if there was no tax or tip.

jack wants to leave an 18% tip, The amount of tip that jack wants to leave is 18/100 * 45 = 0.18*45 = $8.1

To determine how much jack needs to pay including the tip,

Amount that jack would pay is bill + tip = 45 + 8.1 = $53.1

Another way of calculating it is,

Since the tip is 18% and his bill was 100%, we will add the percentages and multiply by the bill. It becomes

118/100 * 45 = $53.1
