Well if the t-shirts are the same amount of money per shirt, then you simply work it out like this.
EXAMPLE
1 t-shirt = $10
So if you need to buy 10 you just multiply 10 by 10.
10x10= $100
Also if you need to find the difference between buying 6 or 10 you subtract the two numbers which would be 4 then divide 100 by 4.

1/2 I think is the answer
Answer:
13 quarters, 26 nickels.
Step-by-step explanation:
n will be number of nickels, q will be number of quarters, and we have 39 total coins
so n + q = 39 (number of nickels + number of quarters = 39 coins.
The problem also says there are twice as many nickels as quarters. so we can call the number of nickels n or we can call it 2q (2 times the number of quarters)
which means
n + q = 39
2q + q = 39
3q = 39
q = 13
and she has 2 times as many nickels as quarters... 2 x 13 = 26 nickels
LMK if you have questions.
If you want to double check the money,
n(0.05) + q(0.25) = 4.55 is the equation to use.
26(0.05) + 13(0.25) = 1.3 + 3.25 = $4.55
