Tickets to a baseball game are $9 for adults. A child's ticket is $2 more than half the price of an adult's ticket. Melanie buys 4 adult tickets an some children's tickets. If she paid $75 for the tickets, how many children's tickets did she buy A. 3 B. 4 C.5 D. 6

Answer 1

Answer: We are given a word problem, which has the following information:

Information related to tickets:

Adult tickets cost $9 each and children tickets cost $2 plus of the price of ticket for adults:

Scenario, Melanie:

She bought 4 Adult tickets and unknown children tickets, but she paid a total of $75!

In Mathematics this can be translated as:

`\begin{gathered} A=9 \\ C=(1)/(2)A+2=6.5 \\ 4A+xC=75 \\ \therefore\rightarrow \\ 4\cdot(9)+x\cdot(6.5)=75 \\ \rightarrow\therefore\rightarrow \\ x=(75-(9\cdot4))/(6.5)=(75-36)/(6.5)=(39)/(6.5)=6 \end{gathered}`

Therefore "x" or the number of children tickets are '6'
