Question

a museum opened at 8:00 a.m. in the first hour, 350 purchased admission tickets. in the second hour, 20% more people purchased admission tickets than in the first hour. how many tickets were sold in the second hour?a) 70 ticketsb) 420 ticketsc) 770 ticketsd) 280 tickets

Answer 1

Step 1. Since in the first hour, 350 tickets were purchased, and in the second hour 20% more people purchased tickets, we need to find how much 20% of 350.

We find this percentage by dividing 350 by 100 and then multiplying by the percentage we want, in this case, we multiply by 20:

`(350)/(100)*20`

Solving the operations:

`3.50*20=70`

70 more tickets were sold in the second hour.

Step 2. Since we are not asked for how many more tickets, but the total of tickets sold in the second hour, we have to add 70 to the number of tickets sold in the first hour:

`350+70=420`

420 tickets were sold in the second hour.

Answer: b)420 tickets
