The pattern oh the problem is 24,23 so subtract 1 every time
Recall the compound interest formula

Where r = 0.04, n = 12 since compounded monthly, t = 30, and p, initial value, is 24000.
Plug them in, 79523.95 seems to be the solution.

Answer:
Step-by-step explanation:
Surface area = lateral area + 2(area of base)
Lateral area = perimeter of base * height.
Because it is a isosceles right triangle, both sides are equal.
= 72
2
= 72. Divide both sides by 2
= 36. Square both sides.
x = 6.
So the perimeter of the base = 6 + 6 +
= 20.485281374239
Lateral area = 20.485281374239 * 7 = 143.397 
Area of base is (1/2)base * height.
(1/2)(6)(6) = 18
Using the surface area formula
surface area = 143.397 + 2(18) = 179.4
