(x+7)(x+9)
Do this math problem by using the Foil method.​

Foil:
First term
Outer term
Inner term
Last term

By using foil we just times the first terms together so: x*x=x^2

Then we times the outer terms together so: x*9=9x

Then we times the inner terms together so:7*x=7x

Finally we times the last terms together so: 7*9=63

So our equation is:
X^2+9x+7x+63

Now we collect the like terms

x^2+16x+63

Let the cost of each shirt be s.

Would assume each  shirt was discounted by 3.66

Amount to be paid for each:    s - 3.66

Total =    3*(s - 3.66)

3*(s - 3.66) = 62.31

s - 3.66 = 62.31/3

s - 3.66 =  20.77

s = 20.77 + 3.66

s = 24.43

Each shirt cost $24.43  before the discount.
