Answer 2

do you have the 2 equations set up?

Answer 3

So this is what I have:
\[70($28) + 15s = $1440\]

Answer 4

70 is the number of t-shirts and sweatshirts combined

Answer 5

x = # of sweatshirts
y = # of t shirts

x+y = 70

Answer 6

`sweatshirts cost $28 and tee shirts cost $15 and William spent $1440`

28x + 15y = 1440

is the other equation

Answer 7

Oh okay
