For this case we have the following equations:
y = 60x + 40
y = 50x + 80
Equaling both equations we have:
60x + 40 = 50x + 80
From here, we clear the value of x:
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 weeks
Substituting x = 4 in any of the equations we have:
y = 60 (4) + 40
y = 240 + 40
y = 280 $
Answer:
$ 280 4 weeks

It is 5.8 that is the answer
Answer:
x = 63.4
Step-by-step explanation:
Here, we want to find the value of x
To do this , we use the appropriate trigonometric ratio
The side facing x is 12, this is called the opposite
6 is the third side and it is called the adjacent
The trigonometric identity that links both is tan
Tan is the ratio of the opposite to the adjacent
Thus,
tan x = 12/6
tan x = 2
x = tan^-1 (2)
x = 63.4
