I have 30 coins consisting of nickels, dimes and quarters. The total value of the coins is $4.60. there are two more dimes than
aleksklad [387]

If you have 1 nickle, how many quarters do you have? (3)

If you have 4 nickles, you have 3 times as many quarters (3)(4) = 12

If you have n nickles, then you have 3n quarters so 3n = q, you have  a slightly different equation.

 

If you fix this equation and use substitution like you did, you can get the right answer; you can also try to work in the other information that you have - converting all coin values to cents

    5n + 10d + 25q = 460

HELP ASAP NEEED THE CORRECT ANSWER
Tatiana [17]

The right answer is Option A.

Step-by-step explanation:

Given,

Amount in Jason's account = $300

Bills paid = \frac{1}{4}

Remaining balance after bills = -$50

Let,

x be the amount of bills.

Amount in account - Bills paid*Amount of bills = Remaining balance

300-\frac{1}{4}x=-50\\-\frac{1}{4}x+300=-50

The equation -\frac{1}{4}x+300=-50 can be used to find x.

The right answer is Option A.
