I am guessing you are talking about Option 3. They start with $125. So they times it by 1.25 as we are using the multiplier method. So in the First month, it will be 156.25. Second it will be 195.3125. So in August it will be $476.837157. Of couse round it and you will get $476.84.
I believe there is a more efficent way of doing this but I have forgotten.

Answer:
22. The surface area is 1/9 of its original value
24. The surface area is 120 m^2 less than its original value.
Step-by-step explanation:
22. For similar figures, the surface area is proportional to the square of the linear dimension scale factor. Multiplying all linear dimensions by 1/3 will result in reducing the surface area to (1/3)^2 = 1/9 of its original value.
__
24. As above, the scaled base surface area will be (1/4)^2 = 1/16 of its original value. Since one dimension of the lateral area is multiplied by 4 and the other dimension is multiplied by 1/4, the net effect on that area is multiplication by (1/4)(4) = 1. That is, the lateral area will remain unchanged.
The overall surface area will be reduced by 15/16 of the area of the bases. The area of the bases is (2)(1/2)(8 m)(16 m) = 128 m^2. The changed figure will have a surface area that is 120 m^2 smaller.
Answer:
Option (a) is correct.
The solution for the given inequality 6x - 5 > -29 is x > -4 .
Step-by-step explanation:
Consider the given inequality
6x - 5 > -29
We need to solve the above inequality to find a solution for x ,
First adding 5 both side , we get,
⇒ 6x -5 + 5 > -29 + 5
⇒ 6x > - 24
Divide both sides by 6 , we get,
⇒ x > -4
Thus, Option (a) is correct.
The solution for the given inequality 6x - 5 > -29 is x > -4 .
