The correct expressions are:
5.3d
5d+0.3d
5(d+0.06d)
Since he is purchasing 5 towels that have a cost of d dollars each, the cost of the towels is given by 5d.
However, to add 6% tax, we multiply this by 0.06 and add it to the price without tax:
5d+0.06(5d)
Simplifying this, we have 5d+0.3d = 5.3d.
All of the correct answers simplify to this expression.
I belive it would be 12x + 12y
Answer is slope of 5
Step by step
You can graph the slope as seen on the attached picture. You go up 30, you go right +6. Slope is y/x, so 30/6, equals 5
You can also use the slope formula
(y2-y1) over (x2-x1)
Using points on the graph
(6,0) and (0,-30)
(-30-0 ) over (0-6)
-30 over -6
-30/-6
= 5
The corresponding answers for each student plan are:
plan A: 15 years
plan B: 5 years
plan C: 10 years
plan D: 9 years
Thus, first, the graph corresponding to each of the plans must be analyzed. The Y-axis corresponds to money and the x-axis corresponds to the time in years.
Thus, in-plane A, it can be observed that to reach the desired value, the graph will be projected in exponential, so it will be close to 15 years. In plan B, this projection will be reached around 5 years. In plans C and D, this projection will be 10 years and 9 years respectively.
