Answer:
The correct option is C
Step-by-step explanation:
Lets find the linear equations:
For Hours
Let
Number of hours in bookstore per week = x
Number of hours for babysitting per week = y
Total number of hours ≤ 16
So the first equation us:
x + y ≤ 16
y ≤ 16 - x
For Money
Let
Amount earned per hour from bookstore = $4
Total Amount earned from bookstore = 4x
Amount earned per hour from babysitting = $8
Total Amount earned from babysitting = 8y
Total Amount earned ≥ $56
So the second equation is:
4x + 8y ≥ 56
8y ≥ -4x + 56
y ≥ -(1/2)x + 7
Cos20=opp/hyp
cos20=19/x
x=19/cos20
