Answer:
64.0%
Explanation:
First step is to find the total cost to make the pins. The pins cost 1.10 to make at 1000 pins
1.10 * 1000 = 1100
This is the total cost
Now we need to find how much money was made
35% were given to charity (no money made)
That means .35 * 1000 = 350 were given away
1000-350 = 650 are left
60% of those are sold at 3 each
.60 * 650 = 390
That means 390 were sold at 3 each
3 * 390 = 1170 were made on these
40% were sold at 2 for 5 or 2.50 each
.40 * 650 = 260
There were 260 sold at 2.50
260 * 2.5 = 650
The total money that came in = 1170+650 = 1820
Profit = money in minus cost
Remember the cost was 1100
Profit = 1820-1110
Profit = 710
Percent profit = profit/ cost
=710/1110
=.63963964
To one decimal place
64.0%
