Answer:
He can buy <u>3 bracelets</u>.
Step-by-step explanation:
Given:
Mr. Gonzales has only 42.50 to spend he wants to buy 29 t shirts including tax and some bracelets that cost 4.50 each including tax.
Now, to find the number of bracelets he can buy.
Let the number of bracelets he can buy be
Price of each bracelets = 4.50.
Total amount to spend = 42.50.
Number of t-shirts = 29.
Now, to get the number of bracelets we put an equation:
<em>Subtracting both sides by 29 we get:</em>
<em /><em />
<em>Dividing both sides by 4.50 we get:</em>
<u>The number of bracelets = 3.</u>
Therefore, he can buy 3 bracelets.
For this case, what we can do is calculate an average of the time it takes to fill the tank for both pipes.
We have then:
taver = (tA + tB) / (2)
Where,
taver: average time (both pipes)
tA: time it takes the pipe A
tB: time taken by pipe B
Substituting the values:
9.9 = (18 + tB) / (2)
Clear tB:
tB = (2 * (9.9)) - 18
tB = 1.8 hours
Answer:
it takes pipe B, running alone, to fill the tank about 1.8 hours
