Question

during spring break a class of 14 children went to walt disney world in florida the price for each child's ticket was &75 while each adult ticket was $85 if the total amount spent on tickets was $1,475 how many adults went on the trip?

Answer 1

hello

cost of the adult tickets = $85

cost of children ticket = $75

let the number of adults be represented by x

let the number of children be represented by y

total number of children that attended = 14

total number of adults that attended = ?

total amount spent on ticket = $1,475

`\begin{gathered} 85x+75y=1475 \\ y\text{ = 14} \\ \text{let's put y into the equation above} \\ 85x+75(14)=1475 \\ 85x+1050=1475 \\ 85x=1475-1050 \\ 85x=425 \\ \text{divide both sides by 85} \\ (85x)/(85)=(425)/(85) \\ x=5 \end{gathered}`

only 5 adults went on the trip
