Elsie is starting a recycling club at her school and hopes to use the money earned from recycling cans to buy recycling bins for the school.
Elsie first needs to figure out how much the cans that can be collected at her school will weigh, so she starts by weighing the cans in her recycling bin at home. She finds that 50 cans weigh 0.77 kg. The next day, Elsie counts cans at school and finds that her fellow students throw away 1240 cans each day.
In order to buy recycling bins for her school, Elsie plans to collect empty aluminum cans in big plastic bags and drive them to a local recycling center. Elsie wants to figure out how many days she will need to use plastic bags before she can buy the recycling bins.
a. The recycling center pays 25 cents per kg for aluminum cans. If her school recycles 2070 cans each day, how much money will Elsie earn each day by recycling?
The drama club has 41 members. There are 9 more girls than boys. How many boys are in the club?
16 boys
To calculate how much money Elsie will earn each day by recycling, we need to determine the weight of the aluminum cans that her school will recycle each day.
Given that Elsie found that 50 cans weigh 0.77 kg, we can calculate the average weight of each can:
Average weight per can = 0.77 kg / 50 cans = 0.0154 kg per can
Now we can calculate the weight of the 2070 cans that her school will recycle each day:
Weight of 2070 cans = 0.0154 kg per can * 2070 cans = 31.878 kg
The recycling center pays 25 cents per kg for aluminum cans, so we can calculate how much money Elsie will earn each day:
Money earned per day = 31.878 kg * 25 cents/kg = $7.97
Therefore, Elsie will earn $7.97 each day by recycling.
