7. This means the cost of the item to you is $52.85. You will pay $52.85 for a item with original price of $75.50 when discounted 30%.

If you buy an item at $75.50 with 30% discount, you will pay 75.50 - 22.65 = 52.85 dollars.

8. Same principle applies

40.99×25/100=10.25

Therefore, 40.99-10.25= 30.74 dollars

9. 30×40/100= 12

30-12= 18 dollars

18a

step-by-step explanation:

simply because it is. it's the highest common factor

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
