Solution:
Ounces of Sugar used by Amanda to make 75 cupcakes = 45 Ounces
As, number of ounces of sugar is in Direct variation with number of cupcakes.

SQ is not a diameter, if it was SOQ would need to be 90˚(angle at a semicircle)
I'm really not sure but my guess would be C :/
3,000 ÷ 10 = 300
the way to check if it's correct is to multiply your answer and the number you divided 3,000 by.
The answer is 300
