You have q quarters, d dimes, and n nickels. you then pay for candy with 4 quarters, 5 dimes, and 6 nickels. write an expression for how much money you have in cents after the purchase.

In cents, before you buy the candy, you have 25q, + 10d +5n. The numbers represent the amount of money each coin is worth, and the variable represents how many of each coin there are.

The amount you spend on candy: 4(25) + 5(10) + 6(5) = 180.

Therefore, after you purchase the candy, you have 180 - 25q + 10d + 5n.

I hope this helps!

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
