Question

The parents club wants to sell buttons to raise money for the local community center sports program. The buttons cost 50 cents each,and the club buys 1,400 of them. How much total profit will they make if they charge $3.50 for each button and sell all of the buttons?

Answer 1

4200

1400 X .50 = 700 

1400 X 3.50 = 4900 

4900 - 700 = 4200

Answer 2

If it costs $3.50 to buy and 50¢ to make, then the profit for one is $3.
Selling 1,400 of them would be solved by 1,400 x 3.
This equals 4,200.
So if they sell all the buttons, they would make a profit of $4,200.

Hope this helps :)
