Answer: 5/7</h3>
Explanation:
I'm assuming the equation is 
which is the same as writing y = (5/7)x.
If so, then the constant of proportionality is the fraction out front: The value 5/7 is the coefficient of the term (5/7)x.
All direct proportion equations are of the form y = kx, where k is the constant of proportionality. Another example would be y = 12x and this time k = 12.
Bye esrimating $225 and that would be $200 to the nearest estimate
Answer:
x = 6
Step-by-step explanation:
Coach ticket = $180
first class ticket = $1020
people = 8
Let x be number of coach tickets
Then number of first class tickets = (8 - x)
x * 180 + (8 - x) * 1020 = 3120
180 X + 8 * 1020 - 1020 x = 3120
180 x + 8160 - 1020 x = 3120
180 x - 1020 x = 3120 -8160
- 840 x = - 5040
840 x = 5040
x = 6
So 6 coach class tickets and 2 first class tickets
We are given that:
i- The store is having 20% off sale
ii- Trina has a 10% coupon
Therefore, Trina will be having a discount = 20 + 10 = 30% of the bike's price
This means that:
Trina will pay 100% - 30% = 70% of the price
We are given that:
The original price of the bike = <span>$89.75
We now know that:
Trina will pay 70% of its price
Therefore:
Final price = 70% * </span>89.75 = 0.7 * <span>89.75
Final price = $62.825
Hope this helps :)</span>
