Question

A museum opened at 8:00 am. In the first hour, 125 people purchased admission tickets. In the second hour, 20% more people purchased admission tickets than in the first hour. Each admission ticket cost $9.50. How much money did the museum make on total ticket sales in the first two hours?

Answer 1

we must calculate the people who bought the ticket

we must add the people of the first hour together with the people of the second hour

if in the second hour there were 20% more people it means that they were 120% in the second hour

so the sum of the first hour and second hour is

`\begin{gathered} 125+(125*(120)/(100)) \\ \\ 125+(150)=275 \end{gathered}`

the total number of people in the first two hours was 275

now multiply the number of people by the cost of ticket to find the total

`275*9.50=2612.50`

the total money was $2,612.50
