-10x=-12x + 21 + 11
-10x= -12 + 32
-10x + 12x = 32
2x = 32
X = 32/2
They basically make a profit of $2.85. Because $9.95 - $7.10 = $2.85.
To break even you would have to sell 4000 footballs. Because 11,400 / 2.85 = 4000.

where r is constant of proportional.
Given that,
y= 27 and x=9
Plug y= 27 and x=9 in above relation





The relation between x and y is

I’m 99% sure the answer is:
c: 2t - d = 260
t - d = 320
