Answer

Explanation:

Step1: Calculate the bill after tax

The dinner cost is $21. Tax rate is 6% or 0.06. The amount of tax is $21\times0.06 = 1.26$. The bill after tax is $21\times(1 + 0.06)=21\times1.06 = 22.26$.

Step2: Calculate the bill after tip

They give a 15% or 0.15 tip on the bill after tax. The amount of tip is $22.26\times0.15=3.339$. The total bill after tip is $22.26\times(1 + 0.15)=22.26\times1.15 = 25.60$.

Step3: Compare with the money they have

They have $30. Since $25.60<30$, they have enough money.

Answer:

Yes. They have enough to pay their bill: $21\times1.06 = 22.26$ and $22.26\times1.15 = 25.60$.
