Respuesta :
Total amount Celeste had initially to pay for lunch = $40
Percentage of money she pays as tips = 16%
Now let us find amount she pays as tip:
Finding 16% of 40,
0.16 *40 = 6.4
So Celeste pays $6.4 as tip.
Now let us find what is left with Celeste after paying tip.
Amount left for lunch = Amount she had initially - Amount paid as tip
Amount for lunch = 40 - 6.4 = 33.6
Rounding off 33.6 we have 34.
Answer : Celeste can spend 34 dollars on lunch.
