Answer:
28 blue bikes
Step-by-step explanation:
There follows a relatively simple method for solving this problem:
Let c be a counter. Then 4c + 5c = 63, and 9c = 63. Thus, c = 7.
Then the number of blue bikes is 4(7) = 28, and the number of black ones is 5(7) = 35. Note that 28 + 35 comes to 63.
There are 28 blue bikes.
First, multiply the number of feet it takes for one balloon by the number of balloons filled daily.
0.5 * 80 = 40
So, 40 cubic feet is 20% of one tank. Now, unless you remember how to find what 40 is 20% of, simply play around with some numbers on your calculator until you find that 200 * 0.20 = 40. I would love to explain how to find that part with an actual formula, but I don't remember how. :/ Hope this helped.
