  Okay so first we need to find 40% of 7.50. To do this you simply divide the percentage by 100, so you have .4 now. You multiply 7.50 by .4 and get 3. Lastly, you just subtract 3 from 7.50 and you get $4.50

Emma will pay $4.50 after the discount.

So, what you need to do is 7.50 x .40 which is 3...

now minus that from 7.50.

7.50 - 3 = 4.50

So with the stores discount she will actually pay $4.50 for $7.50 worth of candy.
