Answer:
1/3 =5x-2
3(1/3)=3(5x-2)
1=15x-6
7=15x
x=7/15 (7/15 , 1/3)
Step-by-step explanation:
Answer:
3.471 + 7.2516 x
Step-by-step explanation:
Given the data:
(1,3) (2,0) (5,-8) (9, -25) .
X:
1
2
5
9
Y:
3
0
-8
-25
The line of best fit for the data given can be obtained using an online regression calculator :
The equation of best fit for the data is thus;
Best fit equation; y = -3.471 + 7.2516x
Intercept = - 3.471 ;
Slope = 7.2516
Divide the price by the quantity:
Bananas = 5.40 / 6 = 0.90 each
Oranges = 2.56/8 = 0.32 each
Apples = 4.68 / 12 = 0.39 each
Mangos = 3.16 / 4 = 0.79 each
Oranges have the lowest price each so are the best buy.

9.8 weeks -> round up you can't have .8 of a week... 10 weeks.
Amy must work at least 10 weeks to make 500 dollars </span>
