Answer:
Julie made $3 /hour more than Loren
Step-by-step explanation:
Loren makes 18 /2 = 9 ($9 / hour constant ratio)
Julie: 36 /3 = 12 ($12 / hour)
Julie - Loren = 12 -9 = 3
? in Loren's : 126, 144
? in Julie's : 72, 252
The answer is 18.
Show your work: You first need to find 25% of 80. To do that you need to remember that percent means per one hundred. Knowing this you need to do 25 divided by one hundred. This equals 0.25. Now to find the answer you will need to multiply both 0.25 and 80 to find 25% of 80. This will equal 20.
Now you will need to do the same with 10% of 20. 10 divided by 100 = 0.1 and times that by 20 = 2.
That will be how many boys are wearing ear plugs. To get the girls, all you will need is to subtract 2 from 20 = 18.
That’s why there is 18 girls wearing ear plugs.
