A collection of 109 coins is made up of quarters, dimes, and nickels. There are 7 fewer dimes than quarters and 3 less than five times as many nickels as dimes. Find the amount of the collection.

The amount of collection is $ 10.60

Step-by-step explanation:

If the number of quarters is x, the equation is x+(x-7)+(5(x-7)-3)=109.

7x-45=109

7x=154

x=22

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
