To find out how many magazines we need to sell to raise enough money, we need to set up an equation. We can use T for total, c for the cost of a magazine, and n for the number of magazines.
T = cn
Now, we know T=600 and c=2.75. Let's substitute and solve.
Since we can only buy a whole number of magazines, we need to round up in order to make sure we get at least $600. Therefore, they need to sell 219 magazines.
