193= 190
149= 150
193+228+149=190+228+150
= 568
61/75=0.81. 1/15=0.06. So 61/75 is greater.
Answer: 5 days
Step-by-step explanation:
12/3=4 souvenirs a day
20/4=5 days
Make sure D is by its self so
90=6(d-84)
Divide both sides by 6 to get rid of 6 from the right side so
90/6= (d-84)
15 =(d-84)
Now get rid of the 84 by adding it
15+84= d
99=d therefore d is equal to 99
