1.)
Old Number:35
New Number:45
Now, subract the new number(45) from the old number. (35)
45-35 is 10. Now divide the old number (35) by 10.
You'll get 3.5. 3.5%, increase is the answer for #1.
2.) Old: s (students)
New: 36,750
Do 100+5 (Addition because we do not know what the old number is.) 100+5 is 105. Move decimal over twice and you get 1.05. Multiply 36,750 by 1.05.
There were 38,587.5 kids last year.
3.)Since the discount is 15% off, do 100-15=85. Now, move the decimal over from the percent, and that makes that .85. Now multiply 50x.85. You get 42.5, or $42.50. Now the coupon is 10%, So subtract 100-10, giving you 90. Now move the decimal over. .90. Multiply 42.5 (or 42.50) by .90. You get 38.25. You do have enough money.
4.) Subtract 100-15, giving you 85. Move decimal over from percent. .85.
Now you would multiply .85 times k. B should be the answer.

Answer:
Step-by-step explanation:
Given: Edge length of cube = 
To find: Volume of the rectangular prism
Solution:
A cube is a three-dimensional solid object which has 12 edges, 8 vertices and 6 faces.
A rectangular prism is a solid three-dimensional object which has six faces that are rectangles.
Let n denotes number of cubes inside the rectangular prism
Volume of one cube = 
cubic inches
So, volume of rectangular prism = volume of n cubes =
1,743 rounded to the nearest ten is 1,740.
