Answer: 7 hours.
Step-by-step explanation:
The rental price is 15. Add 5 per hour (5x) and the total must be equal to $50
15+5x=50
Solve for x;

G(x) = 3x + 2(x + 1)
g(7) = 3(7) + 2(7 + 1)
g(7) = 21 + 2(8)
g(7) = 21 + 16
g(7) = 37
Answer:
√11
Step-by-step explanation:
4 = x^2 -7
Add 7 to both sides
11 = x^2
Square root both sides
√11 = x
That would be a $14.13 tip
so 78.52+14.12= 92.65
$92.65
