If just two points are drawn you have a basic line
1st job $8.50 per hour
if h hours is worked per week in the restaurant, hence the total amount in the restaurant
= 8.5*h = 8.5h
For cleaning the house once a week to earn $25
Total from the two jobs = (8.5h + 25)
(h) = (8.5h + 25)
if 12 hours and 45 minutes was scheduled for the week.
h =12 hours 45 minutes; 45 minutes = 3/4 hour = 0.75 hour
h =12 hours 45 minutes = 12 + 0.75 = 12.75 hours.
(h) = (8.5h + 25) h = 12.75
(h) = (8.5*12.75 + 25)
(h) = (8.5*12.75 + 25) = 108.375 + 25 = 133.375 <span>≈ $133.38
So the answer is option
</span>
<span>d. (ℎ) = 8.5ℎ + 25; $133.38</span>
Hope this explains it.
Given :
A holiday meal cost 12.50 a person plus a delivery fee of $30 at we cater.
The same meal cost $15 a person with no fee at Good Eats.
To Find :
When does we cater become the better deal.
Solution :
Let , x is number of order .
Cost at cater , C = 12.5x + 30 .
Cost at Good Eats , G = 15x .
We need to find :
G > C
Therefore, after 12th order cater will be more value for money.
Hence, this is the required solution.

Answer:
(x, y) = (1/2, 5)
Step-by-step explanation:
We observe that the y-terms have coefficients 7 and -14. If we want to eliminate the y-terms, we need to multiply 7 by a factor that makes it be the opposite of -14. That factor will be -(-14)/7 = 2.
After multiplying the first equation by 2, we have ...
- 16x +14y = 78
- 4x -14y = -68
Adding these two equations gives ...
20x = 10
Solving for x, we need to divide by 20:
x = 10/20 = 1/2
Substituting this into the first equation, we get ...
8(1/2) +7y = 39
7y = 35 . . . . . . subtract 4
y = 35/7 = 5 . . . divide by 7
Then the solution is (x, y) = (1/2, 5).
_____
<em>Check</em>
We used the first equation to find y, so we know the x- and y-values satisfy the first equation. We need to check the result using the second equation.
4(1/2) -14(5) = -68
2 -70 = -68 . . . . . . . true; result checks OK
