30-8.25= 21.75
21.75/3.75= 5.8, you can't buy .8 of a soda so he could buy 5 sodas.
90 x .80= 72. 72 Students like hot choco, therefore 8 do no like hot choco
14.08 that’s if in this case “of” means multiply hope this helps
Answer:
125 Dollars
Step-by-step explanation:
Total fee = 7000
Amount in hand = 4000
Amount to be saved in 2 years = 7000 - 4000 = 3000
No of months in 2 years = 12 x 2 = 24
Per month saving = 3000 / 24 = 125 $
So you want to set up an equation for a weighted average. You know the final is 30% of the grade, so everything else is 70%. This gives you:
(Final)(.30) + (other grades)(.70) = course grade
The best grade the student can get would be if they get a hundred on the final, since that’s the best score you can make on the final. Then,
(100)(.30) + (82)(.70) = course grade
30 + 57.4 = course grade = 87.4 Which, If you round, the student would get an 87.
For the last part, we use the same equation, just filling in different parts.
(Final)(.30) + (other grades)(.70) = course grade
This time, we don’t know the grade for the final, but we know the course grade.
(Final)(.30) + (82)(.70) = 75
(Final)(.30) + 57.4 = 75
(Final)(.30) = 17.6
Final = (17.6)/(.30)
Final = 58.667 Which is approx a 59.
