Let 
be the most the manager can pay the suppliers.
Then, we know from the information given in the question that the manager needs a 30% markup based on cost.

Answer:
The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14.
If number of nickel = n
number of dimes = 3n
number of quarters = 2n
Amount of nickel = 5n
Amount of dimes = 30n
Amount of quaters = 50n
Total Amount = <span>5n + 30n + 50n = 510
In short, Your Answer would be Option C
Hope this helps!</span>
