Answer:
78 x 160
/100
= 124.8
12 x 325/100
= 39
Step-by-step explanation:
Use the method rise over run (rise/run) that would get you 30/20 and that would equal to 1.5
So there are 20 people in the family.
The total cost of the tickets were $100. Tickets for adults cost $8 and children cost $4.
To find the answer for the number of adults you need to divide the $100 by $8 and do the same for children but divide the $100 by $4.
So 5 of the family members were adults and 15 were children.
5 adults = $40
15 children = $ 60
