Answer:

90

Step-by-step explanation:

Quarters , q = 25 cent

Nickel, n = 5 cent

3 times as many nickels as quarters;

n = 3q

Total value of coins = $12

n + q = $12

0.05n + 0.25q = 12

0.05(3q) + 0.25q = 12

0.15q + 0.25q = 12

0.40q = 12

q = 12 / 0.40

q = 30

n = 3q

n = 3(30)

n = 90

90 nickels

Zolol [24]
She has to buy both binders and notebooks. So, you have to take into account that she has to have both. The closest you can get to $20 while still getting notebooks, is to buy 4 binders. 4 times 4 equals 16. So, she can get 4 binders and 2 notebooks, because then, 2 times 2 equals 4 and 16 plus 4 equals 20.
