Ok, first you subtract 21 from 60.
That gives you 39, so you then divide that by 3.
That gives you 13, so each t-shirt cost $13.
Hope this helps

Answer:
Rsp because it sounds like berries
Step-by-step explanation:
A)
well, she has a total of 70 + 30 tiles, now she's not going to used all of them, just some.
the dark area is 8x5, so is 40 ft², and the light gray area is 8x4 or 32 ft². The total area is then 40 + 32, or 72 ft².
b)
the dark area is an 8x5 rectangle, so is 8*5 or 40, so she'll need 40 dark tiles, but she has 70, so that's fine.
the light gray area is a 8x4 rectangle, 8*4 is 32, but she only has 30 light gray tiles, so she's short 2 light gray tiles.
I don't like algebra masquerading as geometry. Algebra and geometry are connected in interesting ways, but this is boring.
It just says the two little angles add to the big angle,
(2x + 6) + (10x - 5) = 73
Solving,
12x + 1 = 73
12x = 72
x = 6
SQR = 2x+6 = 18 degrees
PQR = 10x -5 = 55 degrees
