Step-by-step explanation: For 5, cross multiply
and
to get 975 girls. Do the same for 6. For 7, it says that the television is $550, and it is only 55% of her savings. Therefore, to find her original amount, you will put 550 in the numerator and x in the denominator, and cross multiply 55/100 to get 1000. For 8, do the same thing, and put 354 for the numerator, x for denominator, 75/100 and cross multiply.
Answer:

Answer:
![Speed = 1.875 miles/hour](https://tex.z-dn.net/?f=Speed%20%20%3D%201.875%20miles%2Fhour)
Step-by-step explanation:
Given
![Speed = 33in/s](https://tex.z-dn.net/?f=Speed%20%3D%2033in%2Fs)
Required
Convert to mile/hour
![1\ inch = 1/63360\ mile](https://tex.z-dn.net/?f=1%5C%20inch%20%3D%201%2F63360%5C%20mile)
![1\sec = 1/3600\ hr](https://tex.z-dn.net/?f=1%5Csec%20%3D%201%2F3600%5C%20hr)
So:
![Speed = 33in/s](https://tex.z-dn.net/?f=Speed%20%3D%2033in%2Fs)
![Speed = \frac{33 * 1/63360}{1/3600}](https://tex.z-dn.net/?f=Speed%20%20%3D%20%5Cfrac%7B33%20%2A%201%2F63360%7D%7B1%2F3600%7D)
![Speed = \frac{33/63360}{1/3600}](https://tex.z-dn.net/?f=Speed%20%20%3D%20%5Cfrac%7B33%2F63360%7D%7B1%2F3600%7D)
![Speed = \frac{33}{63360}/\frac{1}{3600}](https://tex.z-dn.net/?f=Speed%20%20%3D%20%5Cfrac%7B33%7D%7B63360%7D%2F%5Cfrac%7B1%7D%7B3600%7D)
![Speed = \frac{33}{63360} * \frac{3600}{1}](https://tex.z-dn.net/?f=Speed%20%20%3D%20%5Cfrac%7B33%7D%7B63360%7D%20%2A%20%5Cfrac%7B3600%7D%7B1%7D)
![Speed = \frac{33 * 3600}{63360}](https://tex.z-dn.net/?f=Speed%20%20%3D%20%5Cfrac%7B33%20%2A%203600%7D%7B63360%7D)
![Speed = \frac{118800}{63360}](https://tex.z-dn.net/?f=Speed%20%20%3D%20%5Cfrac%7B118800%7D%7B63360%7D)
![Speed = 1.875 miles/hour](https://tex.z-dn.net/?f=Speed%20%20%3D%201.875%20miles%2Fhour)
<em>Hence, John is working at 1875 miles per hour</em>
