To evaluate the expression 2,500 + 100t for t = 12, substitute t = 12 into the expression:

2,500 + 100(12)
= 2,500 + 1,200
= 3,700

Therefore, Ms. Tanaka will earn $3,700 for selling 12 televisions this month.

To evaluate the expression 720 - 10s^2 for s = 7, substitute s = 7 into the expression:

720 - 10(7^2)
= 720 - 10(49)
= 720 - 490
= 230

Therefore, Robert will have 230 square inches of space left for his presentation if he uses squares with 7-inch sides.

To evaluate the expression 7(l + 2w) for l = 5 and w = 2, substitute l = 5 and w = 2 into the expression:

7(5 + 2(2))
= 7(5 + 4)
= 7(9)
= 63

Therefore, the cost for a garden that has a length of 5 yards and a width of 2 yards would be $63.
