Question
A website-hosting service charges businesses a onetime setup fee of $350 plus d dollars for each month. If a business owner paid $1,010 for the first 12 months, including the setup fee, what is the value of d ?
- 25
- 35
- 45
- 55
The correct answer is: 55
Given
The fee of 1 month is = $d
So, the fee of 12 months is = $12d
Given that the fixed charge is = $350
So, the total charge for 12 months is = $ (12d + 350)
According to the question
12d + 350 = 1010
(or) 12d = 1010 – 350
(or) 12d = 660
(or) $ = 
$ = 55

When designing a stairway, an architect can use the riser-tread formula 2h + d = 25, where h is the riser height, in inches, and d is the tread depth, in inches. For any given stairway, the riser heights are the same and the tread depths are the same for all steps in that stairway.
The number of steps in a stairway is the number of its risers. For example, there are 5 steps in the stairway in the figure above. The total rise of a stairway is the sum of the riser heights as shown in the figure.
Some building codes require that, for indoor stairways, the tread depth must be at least 9 inches and the riser height must be at least 5 inches. According to the riser-tread formula, which of the following inequalities represents the set of all possible values for the riser height that meets this code requirement?
