Question

How do you solve for number 18??

Answer 1

Answer:

g = 7

Step-by-step explanation:

Given that:

Total people = students + teachers = 42 + 2

Total people = 44

Total amount = $485

Admission per person = $5

Admission of 44 persons = 44*5 = $220

Bus rental = $230

Total expense = admission + bus rental

Total expense = $220 + $230

Total expense = $450

Remaining amount = total amount - total expense

Remaining amount = $485 - $450 = $35

So if a guest is invited, it will cost $5 for admission

If g is the number of guests, the equation will be:

g($5) = $35

Dividing both sides by 5

g = 35/5

g = 7

So 7 guests can be invited
